Drat it aka “figlet” moments: knit leader mylar sheets +

Such moments may well have to be a new blog topic. In the hope of actually soon having enough time to return to knitting on a more regular basis, I have been reorganizing my supplies. This can be a good thing. I have “found” missing ribber comb wires, tools I had forgotten about, have drawer units that are helping with organization of all the “stuff”,  and that for a while will be contributing to my having to make regular searches for all sorts of things. Then there were all those mylar sheets for knit leaders with garment shapes on them for pieces I cannot even remember making with lovely multi colored lines all over them. One in particular had very fine lines, I guessed perhaps from ink other than that in my go to water soluble pens, so I thought to give removal a shot with some alcohol. Hence a warning: the lines did not disappear on the “outside”, so I flipped the darn sheet over to give erasing a shot on its reverse side and discovered quickly by the lovely blue on the cloth that the measurement grid was quickly and completely removed in any area touched by the alcohol. Another lesson learned. Perhaps an earlier one of great benefit might have been not to wait decades to erase knit leader mylar sheets, no matter what the marking tool as I now explore ” would I ever make this shape once again, ever?” and “what will take these lines off?” on other sheets.

Text problems within posts; wordpress issues

After the latest version update in WordPress I have begun experiencing finding à‚ commonly in areas where a space bar or return key might have been used or in spots where the post was edited, at infrequent times with other added characters added as well. The issue is encountered in older posts from several years ago as well as brand new ones now when reviewing them. The problem appears to be a global one across my site.  I will share when the issue is better understood by me and perhaps solved, along with any method used to achieve any corrections.

5/4/2019 I have often edited or created content in rich text formats, then in turn copying an pasting in the visual editor. It may be that any content that was not simple text generated the symbols upon import and that those were filtered out successfully in older versions of WordPress, but not the new one. I now have a workaround that still requires me to review each post, but the process is amazingly faster. There is a WordPress plugin https://wordpress.org/plugins/tinymce-advanced/ that allows for a search and replace option in visual editing mode. It is available for both classic and Gutenberg. If it is used, each symbol or character set can be found throughout the whole document, a blank can be entered for the replacement of all, and offenders are quickly deleted from post content.
Of course, now that I got this far, I see there will be a brand new release on May 7th with the announcement “One of the most highly anticipated features for v5.2 is the Site Health Check. This feature adds two new pages in the admin interface to help end users maintain a healthy site through common configuration issues and other elements that go along with having a robust online presence. It also provides a standardized location for developers to add debugging information.” uh uh!

I am also not alone in not being fond of Gutenberg, some links to forum discussions: https://wordpress.org/support/plugin/gutenberg/reviews/

At this point, my apparent option is to hand edit every post I have written. The most frustrating part of the process is to locate graphics that now seem to have disappeared, a separate issue. Sigh!

After contacting my web host, it appears they were able to correct the problem. Some of the posts I have reviewed have extra spaces where the unwanted characters used to be and occasional graphics ie charts or photos are ghosted out from the content upon visiting the site. It will take a while for me to get caught up with reviewing remaining posts.  The announced date for my site update to the latest WordPress version is May 22.

  

 

More on Brother DBJ, including KR 260 bulky KM options

Any repeat suitable for a 2 color 24 stitch DBJ separation published or self-drawn for a 4.5mm machine is suitable for DBJ on the bulky. At times yarns ie 2/8 to 3/8 wools that knit stocking stitch at tension 8-10 on the main bed and are too thick for every needle rib on the standard may produce a fabric that is not too dense, and still has some drape at lower settings for tension on both beds on the bulky. Electronic standard knitters can double the size of the repeat prior to separating the 2 colors and then work on every other needle both beds, proceeding as usual for DBJ. Thicker yarns begin to make too thick a fabric for wearables, may work well for other uses. If some drape is required, the ladder back method becomes the preferred one in bulky KM DBJ. I no longer have available the bulky dbj samples from my teaching days, my 260 KM is not set up, so, for now, this post will not include swatch photos. As always swatching is a necessity to determine whether the resulting knit is one that meets our expectation, preferences, and often, patience.

To review: the 260 KH carriage will be familiar to Brother punchcard 4.5 mm machine users and has the option for creating thread lace (“split” cam button in center position), which is not commonly available in Brother models.

The Brother 270 electronic knit carriage offerssimilarsettings

There is no automatic method for eliminating end needle selection ie KCII, rather, adjustments for it are made on the underside of the carriage, as in other punchcard machines terms of DBJ, the electronics allow for the familiar KRC 2 color separationKR 260 parts as described in the ribber manual, followed by possible settings for cam levers are illustrated below. The absence of lili buttons is immediately noticeable. There is no automatic every other needle selection on the bulky ribber carriage shown, as opposed to that choice being available on the standard KM.

hand selection tools for either bed, 4.5mm on top,  sometimes interchangeableevery needle selector for standard, operates similar to Jac 40, EON here for use bulky, adjustable 17.5 inch workshop cut model in a plastic for 2X2 selection on bulky nowadays 3D printed custom options are also beginning to be available

The DBJ setting that requires the least intervention on either standard or bulky machines is the one produced with the separated motif being knit with the ribber set to slip all needles in one direction, and to knit every needle in the other. Reproducing the lili effect is done on the KR 260 is achieved with hand needle selection. For birds eye, where every needle is in use on an even number of needles in work on the ribber, select every other needle on the ribber beginning with the second needle on the right for preselection row, push up to holding position. The ribber carriage is set to slip both ways, will knit hand selected needles as it makes its way to the opposite side. Now select every other needle on the ribber beginning with the first needle on right, bringing those needles up to hold. Stitches on those needles will knit on the ribber as the carriage makes its way back to the left and to the color changer. Colors continue to be changed every 2 rows as in any standard 2 color birdseye fabric. 

Ladderback or modified Jacquard is at times used on standard machines specifically for the effect created on the fabric reverse side, and most often used with bulkier yarns in order to be able to make a garment with more drape than it may have in regular jacquard, or to knit large designs with no long floats. This technique on the KR 260 ribber involves hand manipulation of the ribber stitches to reduce the number of stitches created on the ribber as well. Ribbing is often set up in order to produce a band that is not hugely different in stretch and width than the body of a garment, with further transfers for the ladder back configuration when it is completed. No more than one needle is usually in work on the main bed beyond needles in work on the ribber bed. If an additional needle on the main bed is required, it should be on the left-hand side. The rib is knit as tightly as possible, tension is loosened as one progresses into the jacquard portion of the piece. Common arrangements are 1X1, 1X3, 2X2, etc.  When needles are arranged in “even groups” ie 2X2, 2X4, 4X2, etc, the lili setting or manual needle selection to emulate it on the 260 may be used. Tuck settings may be experimented with as well, but tend to create a more noticeable vertical line between ribbed repeats on the knit face. The larger the number of needles in work on the main bed between ribber needles in work, the more the main bed tension needs to approach that used for the yarn when it is knit single bed. 

In EON ladder back an increase on the ribber is usually necessary after 4 increases on the main bed. On the bulky, this may be needed as often as in every 2 rows. The hand needle selection must remain constant throughout the piece to maintain the birdseye backing or any of its variants, which are based on pairs of needles alternating functions every 2 rows. Striper backing is achieved by selection of the same needle for each of the 2 colors used, slipping the opposite color needle locations. First needle selection on right is easier to track by marking the location of the first needle used on that side on the needle tape or needle bed as a guide for subsequent rows. 

The row counter will show double the number of rows than if the fabric were produced in Fair Isle. Four passes of the carriages complete one design row. The motif will appear elongated to a degree depending on the yarn and techniques used. Ladder back and vertical stripe backings may produce vertical separation lines in the fabric that may be quite noticeable depending on color, tension, and yarn used. Watch closely for dropped stitches or split ones. Splices and knots in yarn may tend to break due to use of added weights and tension. Plan on adding new yarn at sides and use ends to seam up, or use Russian join before the point at which a new yarn end is required, and continue knitting. The latter has become my favorite even in lace knitting on the standard machine. A recent tutorial on the technique may be found here <https://www.mybluprint.com/article/this-method-of-joining-yarn-ends-is-pure-magic>

Check alignment and oiling requirement of machine frequently. 

Other backings: one color backing. The main bed is set as normal for DBJ, but the ribber is set to knit for 2 rows of one color, and to slip for 2 rows with the other color. This means on any machine (unless using 2 electronic carriages as described in another post) the operator has to change ribber settings every 2 rows. It will now take 4 carriage passes to complete 2 rows of knitting. Floats will be formed in the non-backing color, may be caught on the ribber on slip rows, so check frequently, begin with small repeats, always test new yarns or even a different color or dye lot in same yarn on swatches prior to committing to larger pieces. 

Patterned backing: selection of ribber needles in blocks of alternate colors, or selecting ribber needles in between those selected on the main bed applies here as well. Yarn thickness and end product serve as guides as to whether the fabric serves one’s purpose or preference.

In large areas of solid color on garment face, if bleed through is noticeable, a pattern of 2 black rows alternating 2 white ones may need to be programmed, with color changes continuing as in pattern areas. If the goal is simply to match density or drape, then continue in settings used for design area without color changing. Most punchcard double jacquard separations and “rules” apply to both standard and bulky machines.

Later posts: ribber bind offs at first, and casting on. I was never quite content with ribbed edgings on my bulky knits. There are always several options for achieving a look that pleases us more, or a technique that will alter the unwanted results. In this instance, one is to knit a row on the main bed after several rows of waste yarn, continue with the body of the garment piece, rehang that first knit row, knit the rib upside down, and bind off. The latter can happen on the machine, by hand off on waste yarn with a “sewing” needle, or removing the work onto hand knitting needles and going that route. The 260 ribber manual recommends the following method. 

Having the waste yarn U style with an opening on right with the bind off beginning on that side, or finding a way to mark the first needle on the ribber in the sequence may make finding that needle position easier when the knit is off the machine.

This illustration, also from a Brother manual, slightly edited, shows the sequence for how the yarn is threaded through the stitches in numbered sequence according to stitch configuration for the ribbed fabric

Ribber fabrics with main bed tuck patterning

WORK IN PROGRESS


Tuck stitches on either bed will force apart the space between vertical rows of stitches in every needle rib, whether the tucking is executed on either or both beds, in one or 2 color knitting. The fabric lies flat, and depending on fiber and thickness of yarn used, the effect can be lacey and have lovely drape. In published repeats, often tucking does not happen for more than 2 rows, making knitting fairly “safe”. In thinner yarns elongation may be used to force the fabric even further apart for a more “open” look. Patterning in suggestions below occurs automatically, and on the main bed only. Needles out of work on the ribber may be planned within repeats to produce a fabric with knit textures on what appear as both knit and purl surfaces. There are designs in pattern books that are promoted as being specific for this purpose, but nearly any tuck pattern may be used once limitations are recognized.

The advice from the Brother Ribber Techniques Book and the KR850 ribber manual respectively is shown below. If a knitting with a very fine yarn, the close knit bar is recommendedAn often forgotten accessory: (I admit I have never used them)

Fine knit bar for using thin yarns

Typical patterns for the fabric from punchcard volumes

In electronic patterning a single isolated repeat will suffice. Punchcards illustrated above show the minimum required length for each. In matching needles out of work on electronics, it matters whether the default setting produces what is seen on the card on the purl or the knit side. Flipping the repeat horizontally may be required.  “Air knitting” with needle selection can help plan exact location on needle bed, as well as repeat width and in choosing of location and type of side edges. Again, having ribbed vertical stripes on each side will help the latter lie flat.

 

Geometric shapes on ribber fabrics with tuck stitches 2; knitting with 4 carriages

When switching between N/N and tuck/ tuck on the ribber it is not necessary to switch the tucking lever from its up position to the lower one. The ribber will knit every row when used in either of these settingsIt is possible to knit this type of fabric using color separations such as those seen for one type of DBJ where color one for each design row knits 2 rows, followed by color 2 for corresponding design row also knitting for 2 rows. Each color may be drawn and programmed once, followed in turn with elongation X2 on both punchcard and electronic machines. I prefer to work with the elongated images, believing it makes it easier for me to correct errors or knitting problems, should they occur. This color separation is the default on Passap. In Brother electronics it would need to be hand done and programmed. It is best to start with simple shapes. This triangle series has been used in several of my previous posts. The chart shows the transitions in the process

Brother DBJ settings using tuck on either bed, not addressing hand needle selection on the ribber for production of reversible fabrics. The yellow color highlights cam settings that require changing by hand for every other pair of knit rows, and making the changes with each color change. With the exception of the bottom 2 the same settings were used in some of my brioche variation experiments. The resulting fabric, knit in reverse order from chart (top setting down to first). The dropped stitches happened when I did not notice the ribber weight was resting on the floor, with no resulting weight on the fabric. There are single repeats of each motif. Two more possible DBJ variations

A full range of DBJ variations of the same repeat, including ones using slip stitch and shared in a previous post, executed in both one and 2 colorsPassap knitters have the option of arrow keys and stitch type on the back bed that make fabrics possible with ease that are daunting to reproduce on Brother machines. There is a category search on my blog that will lead to a collection of posts on the topic of knitting with 2 carriages selecting patterns.

I have often considered the possibility of using 2 coupled knit and rib carriages for some of my patterns but found it limited knit width because of carriage stops on the ribber bed, the unwillingness to have my ribber carriages fly off the bed, and the added limitation imposed when both carriages are selecting needles. Now that setting changes were required every 2 rows on the ribber I found a solution of sorts. It is one of those try at your own risk tips, but for me it made several of the last swatches in brioche achievable far more quickly and accurately.

As in any knitting with pairs of carriages, when needle selection is happening from opposing sides, the turn marks need to be cleared on each side of the machine as the opposing carriage begins to move across the needle bed to avoid breaking the belt.

I happen to be knitting present swatches on my orphaned 930, which still knits producing interesting sounds. It came with no carriages. I am actually using a knit carriage from a 910 and one from my 892E punchcard machine, with a magnet glued to the proper location facing the rear rail. I removed the stopper pins from either side of the ribber bed, placed lace lace extension rails on both sides as well as the color changer with all change buttons released as seen in this illustration. On the left, as the carriages move beyond the end of the needle bed, the return signal lever is tripped, making a characteristic noise. A that point the turn mark on the left has been cleared, and it is safe to operate the carriages from the right toward the left
The right side of the machine is more problematic. The extension rail will store the knit carriage safely, but the ribber carriage has to move out enough so without its stop it would fall to the floor. My solution was to jerri rig an extension the appropriate height so the ribber carriage could slide out as much as needed while being supported. I was able to knit the hundreds of rows required for many swatches with no problem other than operator errors. Here the pair of carriages on the right are seen resting far enough off the machine to clear the belt, at an adequate height for them to slide off and on easily. At first I secured the connecting arm to the connecting pin with an elastic “just in case”, but that proved unnecessary. 

I have been asked lately about the lili setting used in all my ribber carriage illustrations (center position). I tend to use that as a default to prevent errors and for consistent quality in my ribbed fabrics, especially if matching gauge ie in garment pieces or bands is needed. That said, for the carriage to travel far enough on the right in this set up, the slide lever had to be used on I. The plastic tray helped reach the appropriate height, and made for easy slide off and on. There are a few minutes of maneuvering when setting up first selection row. As always it is good to begin with familiar yarn and previous experience with double bed fabrics.

Some of my own operator errors are due to the fact that I still am not used to the fact that the 930 appears to revert to factory defaults with each new design entered, that I have to remember to switch from isolation to all over, that the image is reversed on the knit side like on punchcard machines unless the reverse key is used. I spent decades using the 910, where once the selections were made and once the pattern variation buttons were set, that became the default until buttons were changed for specific applications.

The 2 pairs of carriages may also be used for vertical striper backing using lili buttons on Brother machines, and for both slip and tuck variations of same. I will add information in a separate post. More “patterns” are possible as well, emulating some of the Passap possibilities for its back bed settings.

Lace transfers meet fisherman rib, 2 color ribbed brioche on Brother machines 2

Over the years I have avoided ribber fabrics that involve hand manipulation of stitches in addition to patterning. Runaway stitches are hard to see and repair.

In these fabrics transfers are made by hand with multiple transfer tools. As stitches are moved, the last of the stitches transferred on the purl side (in this illustration 4 stitches), one will lie directly behind one of the stitches on the main bed (marked in red), sharing the same needle hook space. As the next row is knit, the needle emptied by the transfers picks up a loop. The following knit carriage pass will complete the stitch on the needle holding the loop, and the eyelet.

My recent posts reminded me of a repeat from an older Brother punchcard pattern book that combined lace transfers and fisherman rib. The original repeat is shown on the left, designed for use on punchcard machines.Stitch and tuck loop combination transfers are made every 4 rows, prior to knitting that row in the opposite direction. The machine is set for half fisherman rib. Tucking happens on top bed on all needles in one direction only, the ribber remains set to knit both ways throughout.If all transfers originate on the same spot, a vertical line of eyelets is producedCan plaiting give me 2 colors the “easy” way?
If transfers move to the right or the left, an arc will be createdAiming for the punchcard pattern book inspiration I began at first by marking up the needle tape with water soluble pen to help track repeat segmentsAfter a short trial swatch I sought to automate needle selection to serve as a guide for moving stitches across the needle bedThe main bed is set to tuck in both directions. White cells tuck, black cells knit. Rows in Brother preselect for the next row with each pass of the carriage, so on even number design rows as the carriage moves to the opposite side, all needles will form tuck loops on the main bed. The next row will be preselected, with some needles now back in B rather than D position. With an appropriate transfer tool, move the stitches on the non selected needles to the adjacent selected needle to their right after pushing it back to B position. After each transfer push all worked needles and their stitches as well as he now empty needle to E position. As the carriage returns to the opposite side an all knit row will be completed. Several tension adjustments may be needed to insure loops do not get hung up on gate pegs as stitches move across the bed, while still being loose enough to knit off properly.

The charts below reveal planning for a 2 color repeat with mirroring of the original above. Seeking new geometry, the repeat “inspiration” is mirrored horizontally. The final repeat is on far right. The knit carriage is set to tuck in both directions throughout. On white cell design rows the main bed tucks, the ribber is set to knit. On mostly or all black cell rows the main bed will be knitting, the ribber is set to tuck. In this fabric the transfers are made on knit stitches created on the previous row prior to moving the carriage back to the opposite side. All transferred stitches and the empty needle are brought out to E position prior to moving the carriage to the opposite side, will be creating the second all knit main bed row. Transfers are made every 8 rows, with pairs of transfers being made toward each other, no longer all in the same direction as in the single color sampleThe central repeat is color reversed to achieve the final repeat on the above right in order to produce those transfers on knit rows. Final row count needs to be a multiple of 4 rows in height. Here is a 2 widths 36 stitch X 32 row repeat chart The extra line seen occurs when one forgets to reset the ribber to tuck, and stitches are all knit on a “wrong row”. It is by coincidence that they seem to occur in the same spot in the repeat

more accurate knitting

On the bottom half of the swatch below the difference is the result from when one carriage knits every row on both beds, requiring a change on the knit carriage as well, canceling its tuck setting with every other color changeThe last repeat may be flipped vertically as well. It then needs to be edited so those white squares land on the row after an all knit row, not below it. The final repeat on the right is 36 stitches wide by 64 high. There are still 8 rows between transfers. On the left is the first resulting chart, on the right the amended chart so selection for transfers occurs on the proper row.the germ of one last idea, the repeat 14 stitches wide by 96 high, max transfer seven stitches (odd #)playing with ideas a bit more, max transfer six stitches (even#)

This was my attempt to shoot for a recurring shape and planning on having transfers land on a like color, the repeat is 8 stitches in width, 112 rows height. Six stitches are the max number transferred. More would give a wider curve, the final repeat would be exponentially longerits reverse side :
When the main bed tucks in both directions with one color, knits in both directions with the other:I did try to eliminate those lace holes. On the right of the swatch as shown below I threaded a needle and attempted to close the eyelets with stitches, getting closer to the line one might get in a hand knit. On the left I hooked up loops to fill the empty needles. The latter changes the intersecting lines completely.

Tuck stitch meets thread lace repeats and vice versa

A recent share in the Facebook machine knitting group led to this blog post by its author <https://www.knittingmachinemuseum.com/single-post/Knitmaster-580-Electronic>

The inspiration fabric led to ideas for recreating it on a punchcard machine, and my own trip down that rabbit hole led me to thinking about the relationship between tuck stitch designs and thread lace ones.

Not all Brother knitting machine models were equipped with the capacity for thread lace. The 260 bulky happened to be one of those models, which were manufactured with 2 MC buttons seen in this illustration

Studio manuals refer to the fabric as punch lace. Early pattern books including ones for electronic machines provide a large range of pattern repeats for such fabrics, and can be design sources for other knit stitches if one understands the structure being created.

In tuck stitch the unpunched areas, white squares or pixels represent loops created on non selected needles, punched holes / black squares or pixels represent knit stitches. In punch/ thread lace those white areas knit both thick and thin yarns together, while in punched holes/black square or pixel areas the thin yarn knits on the stocking stitch side of the fabric, with the thicker yarn floating behind it. Depending on fiber content, gauge, etc. the illusion of eyelets can be created. This is half of a Brother punchcard repeat, suitable for thread lace, reworked for knitting the design in tuck stitch. That is in turn doubled in length to allow for color or yarn value changes occurring every 2 rows. The resulting swatch is tested first in 2 colors to proof the repeat, then using clear serger thread as one of the 2 “colors” for a very different effect that blends that of both fabrics.

Looking at design sources for possible redesigns for the alternate knit fabric: published punch lace cards

published tuck stitch cardsFor DIY a place to start is with simple color reverse punch lace to tuck test. Not suitable are any areas with lots of side by side white squares. In the bow solid lines those could be modified, most of the repeats in the colored swatch segments of the published charts are unsuitable.

Once the chosen repeat is isolated, the punchcard can be further edited for electronic knitting. Tuck to punch lace: any of these would be worth a test, some results may be very subtle.From punchcard repeat to electronic: strong black and white images that have punched holes represented as dots may be the hardest to process quickly in Gimp. It is best to isolate the single repeat. Some clean up of the gridded image may be required. Test the latter by tiling it. Color reverse the single it if that is the original goal, using built in function in electronics or punching black squares in cards.

Not to be forgotten: the easy variations for visualizing results with a few clicks of a mouse,

and an added source for both stitch types are slip stitch patterns in suitable configurations

Lastly, an earlier post on thread lace on Brother machines

 

Revisiting use of lace patterns Studio vs Brother machines

2011: There are several brand KMs still around and in use, most are no longer being manufactured. Questions often come up on using one KM brand pattern card on another. Card readers inside the machine are below eye level, so exterior number/other markings on cards or mylars reflect that, providing the knitter with a visual cue as to where they are in the repeat. If machines pre select, the needle selection may not bear any relationship to actual design row on the punched card or mylar as opposed to what one sees. In addition to this variable in lace one often has 2 carriages in use. It is possible to develop cards etc. from lace hand knitting graphs, but there is enough going on so a good place where to start experimenting is with pre drawn ones. Lace preselection on any single row may have no obvious relationship to where the lace hole will ultimately end up.
Here are some random facts gathered from both sources and experience, they are applicable only if the knit carriage is set for plain knitting and no other function ie. slip or tuck is involved; plain knit rows do not advance the card reading mechanisms. In mixed structure fabrics the rules change.

The Brother and Toyota lace cards can be used on studio punchcard machines as long as they are patterns which have 2 blank rows after each transfer sequence
Brother and Toyota have u shaped arrows to identify when to knit with the knit carriage, both brands read cards 7 rows down
The first row on Brother is transferred from right to left, while on Toyota it is transferred from left to right; Brother and Toyota cards are interchangeable provided the card is mirrored vertically (or a simple cheat: use carriages on opposite sides of usual)
For Studio knitting find the row number of the U shaped arrow and circle the 2nd and 3d row below that row that number to identify rows in which carriage is changed/set to knit
Brother ends with 2 blank rows
Studio starts with 2 blank rows
on Studio begin brother card by locking card 4 rows before row 1, on row 3
Brother/Knitking lace carriage does not carry yarn, does not knit or trip the row counter; the stitches get transferred in the direction that the lace carriage is being pushed
Studio/Singer has a lace carriage available that transfers as it knits; on more complex laces one is sometimes instructed to set the carriage not to knit for a specified number of rows, the yarn may be removed, other adjustments are often required
though Studio and Brother lace cards are not directly interchangeable; aside from the numbering issue the transfer method is different, so a studio lace card working on brother or vice versa is a happy accident and likely to result in different fabric
Brother information is applicable to its new clone, Taitexma

2013 In this instance I am exploring the use of punchcards that are designed for transferring and knitting at the same time as seen in Studio simple lace in machines such as Brother, where the operation is the result of using 2 different carriages.

the Studio card usedthe resulting fabric

The method: both carriages are used to select needles, use lace extension rails on both sides of the machine. Cancel end needle selection on knit carriage underside if possible, or push end needles back manually if needed to avoid their corresponding stitches being transferred throughout the piece. Set up for knitting the pattern as usual, punchcard row 3 (marked in pencil) becomes row 1 of the design when the above card is used in brother machine. The arrows always indicate the direction the lace carriage will move across the knit to make transfers in the direction of that same arrow.

  1. begin pattern knitting with COR, card locked, change knob on KC, no cam buttons in use. This will result in needle selection, but the fabric produced is in stocking stitch. The lace carriage is engaged o the opposite side, moves toward the knit carriage to make the transfers, as it travels across the bed the now empty needles will once again be in B position.
    2. (lace carriage) travels back to right and is released off the machine (same needle selection appears, but those needles are now emptied of yarn)
    3. COL: KC moves left to right, knitting the single row, all needle hooks now are now full, new needle selection occurs
    4. LCOL: makes transfers toward the knit carriage, and then makes a second pass to return to opposite side and is released.
    These 4 steps are repeated throughout the knit, with the knit carriage knitting and selecting, the lace carriage following its selection to make the required transfers. Not every transfer row will match the direction of the arrows as marked on the studio punchcard.
    If there is no pattern needle selection with the KC pass on any row(s), continue to knit until there is needle selection, and begin process using lace carriage to transfer toward the knit carriage from the opposite side and once again releasing it after its second pass.
    A caution: hesitation and reversal in movement of carriages in Brother machines advances the card in the reader, and results in mistakes in patterning; if errors are to be corrected or such movements need be made for any reason, it is worth locking the card, checking row numbers, remembering to release the card before continuing, and visually checking pattern after the next knit row.

2013: While working out yet another HK to MK lace pattern, I sorted out the following method for using Studio simple lace on the electronic KM. It is a method that does not work on the Brother punchcard to produce the same fabric however; on punchcard machines as either carriage is moved to select from opposite side of the bed, the card will not advance on the first pass, interrupting selection. I tried a swatch and got a very different lace design; depending on the starting pattern the results may be interesting (do not use elongation), but not the ones intended to match any original.

The knitting samples shown below were knit on a Brother 910. On electronic machines, as seen in previous posts on knitting with 2 carriages, the mylar (or otherwise programmed) repeat advances a row with each pass of the carriage, no matter on which side of the bed the pass originates. Dropped stitches are harder to repair in these fabrics than in patterns for multiple transfer lace (there knitting can be unraveled to the start of a sequence where 2 or more knit rows usually occur), so checking transfers, gate pegs, and adjusting stitch size and weights matter even more. There is no need to mirror the image horizontally; draw repeat as is on punchcard onto mylar, all variation buttons down

start knitting with KC (knit carriage) on left, Lace Carriage (LC) on Right program pattern double length
on the first row the LC selects, the next row it will transfer; LC always makes 2 passes first toward the KC, then away from it, even if those 2 rows in repeat have no needle selection. I is then removed from the bed to be returned to the bed on the opposite side after the knit row with KC that follows. In summary:
KC knits a single row to opposite side
*LC is placed back onto machine opposite the KC to make 2 passes, is removed.
KC follows with a single knit row to the opposite side*.  * to* steps are repeated

3 total carriage passes complete one row of knit. The chart below shows actions and placement of carriagesThis sample was knit beginning with lace carriage on left, as can be seen in marked areas, the alternating repeats have a different quality in the sets of transfers marked red vs green
The successful swatch knit beginning with KC on left, LC on right in the method described aboveApril 2019 I attempted the same repeat on the 930 with img2track. I flipped the repeat horizontally and elongated it X 2 prior to knitting it. The arrows in the chart indicate the movement of the lace carriage, beginning with the first preselection row from the left I had issues with the proper needles being selected (proofed also in fair isle), but with random stitches not being transferred. A switch in lace carriages, needle retainer bar, yarn, did not eliminate the problem. I finally had to perform some of the transfers by hand. This swatch also shows the joy of missed dropped stitches in lace knitting, the yarn used is a thin acrylicDecember 7 2018: an interesting method using 2  electronic lace carriages found on youtube . The repeat used in the video is actually the same used in my sample above, programmed using img2track.

There will be no needle selection at the end of each sequence, signaling the need to release the LC, knit one row, and continue with LC brought to opposite side. This is a very fussy knit. At several points it is loops formed on previously empty needles that get transferred rather than full stitches. They love to get hung up on gate pegs. It took a significant amount of time to produce the proof of concept swatch. It is a lovely lace. Knitting it on a punchcard would give one the luxury of frequent pauses and markings to make for additional clues

Geometric shapes on ribber fabrics with tuck stitches 1

The previous post elicited a facebook query as to whether it might be possible to create solid shapes within the field of brioche vertical stripes. The inspiration for the query was a hand knit pattern published in ravelry 

https://www.ravelry.com/patterns/library/pariss-brioche-scarf

Many terms are used in instruction manuals and published directions. In my notes I will refer to fabric with tucking on both beds as full fisherman rib, tucking on one bed only as half fisherman. These were my first attempts at exploring the inspiration idea, the fabric has inherent differences as it requires both slip and tuck stitch settings, so technically it is neither fisherman. Knitting happened on a random drop stitch day, which explains the patterning interruption errors.When attempting to knit isolated geometric areas on a field of frequently tucking stitches, automating the task when possible makes the process easier and faster. This was my first “diamond” pattern repeat, suitable for a punchcard machine as well. The design is illustrated on the left, converted to punched holes/black squares/pixels on the rightThe knit carriage is set to tuck throughout. The programmed repeat will alternate the knit/ tuck functions across the bed based on black squares, punched holes, or pixels.For full fisherman rib (top swatch) the ribber needs to tuck in one direction only, opposite to the action taking place on the main bed. A choice needs to be made on either of these 2 setting directions based on needle selection on the main bed and stays fixed throughout knitting. The ribber is set to knit on even numbered design rows on the card, to tuck on odd. Row count numbers may be different than design row ones depending on row counter settings by the operator or built KM ones. Below are tuck settings for to the right on top, to the left on the bottom.

For half fisherman rib (middle swatch), the ribber is set to knit with every pass.

Note the half fisherman fabric is narrower than the full. Also, I am not used to my 930, overlooked that the machine was set for isolation, so its bottom diamond shaped repeats are incomplete.

In the bottom swatch, I tried to produce a more distinct shape on tubular tuck created with only knit stitches on both sides of the fabric. Hand selection on the alternate beds on all tuck rows produced knit stitches in the desired area. A needle out of work made it easy for me to find a proper location on the needle bed.

Getting back to automating at least part of the process for such shapes: the repeat needs to be altered main bed will be knitting the black squares in the chart on the right on every row, tucking the white ones. When the ribber carriage is on the side appropriate for it to tuck the following row and no needles are selected in design segments on the top bed (odd numbered design rows, ones with majority of black squares, tuck may not be used in those locations because then the resulting stitches would be tucking on both beds with nothing holding the tuck loops down.

bring all needles between selected main bed needles up to hold on the ribber so that they will knit while the remaining needles tuck on the next pass of the carriages.

In my sampling, the ribber was set to tuck when moving from right to left. Below is the resulting swatch, shown on both sides. Part of one diamond shape is missing due to the fact I was concentrating on moving needles around and missed the change in selection on one side of the machine.Back to the original the method used in the previous post where ribber settings are changed from knit to tuck <– –> every 2 rows along with color changes. I chose a design that would make it easy to identify the location of non selected needles on the main bed on rows where ribber will be set to tuck in both directions. The result is interesting, but the solid areas, narrower than the remaining knit, are in the opposite color to the dominant one on each side, the reverse of the inspiration fabric.
When needles are not selected on the main bed, interrupting the every needle selection bring all needles on the ribber between selected needles up to hold on each of the 2 passes from left to right, and right to left. Stitches on those needles will knit rather than tuckresulting in this fabric The first swatch at the top of this post was achieved going a very different route. Two knit carriages were used to select and knit from opposite sides of the machine. Each carried one of the two colors. When working with the first color and coupled carriages the main bed is set to tuck <– –>, the ribber to knit <– –>. The second color is knit using the main bed knit carriage only, set to slip <– –>. A knit sinker plate may be altered and used so as to knit on main bed only rows, adjustments to it are shown in post http://alessandrina.com/2018/04/15/ribber-fabrics-produced-with-2-knit-carriages-selecting-needles/. The chart for my working repeat with a multiple of 4 rows in each pattern segment, color changes every 2 rows indicated on right trying to produce a diamond shape using this technique, my first repeat had arbitrarily placed pixels:the cam settings on the right of the swatch images correspond to those used in each swatch segment. Colors were changed every 2 rows throughout. First 2 rows in the pattern were knit in tuck setting, followed by 2 rows knit in slip. In segment B when no needles were selected on the top bed, all those needles were brought out to hold before knitting to the opposite side. Because every row is now knitting in the corresponding color changes the result is a striped pattern. Segment C is knit with both carriages set for 2 rows as in C1 alternating with knit carriage only set as in C2. At that point the color being carried knits only on the ribber, skipping non selected needles on the top bed, avoiding the striped result. A float is created between the beds in areas where no needles are selected that will be “hidden” as one returns to knitting in rib with 2 carriages. The arrow in the chart points to an area where two colors were picked up with the color swap rather than one. The resulting swatch samples

Analyzing the result in section C: the diamond is the same color on both sides, whereas the initial rectangular shape experiment reverses the colors. Reworking the diamond repeat in segments that are each a multiple of 4 rows:Other considerations in DIY designs. The background-repeat for this pattern is actually composed of units 2 wide by 4 rows high. If the pattern is intended to be repeated across a larger number of stitches on the machine bed than that in the chart, it is always worth tiling the image to pick up any errors (sometimes happy design features). Tiling in width readily shows an errortiling in height as well proofs row intersections as welltiling the corrected width repeat, now 42 stitches wide by 72 rows high sometimes tend not to keep immediate notes when I test ideas, which often comes with a price. I knit my first swatch using this repeat beginning the pattern with 2 rows of tuck, resulting in this fabric (and some randomly dropped stitches once more) with the same color diamond on both sides:Beginning the pattern with 2 rows of slip stitch on the main bed only mirrors the swatch at the start of this post. Where no needles are selected on the main bed, with passes of the combined carriages, two rows of tuck will now be produced, resulting in the wider geometric shapes and the increased bleed throughThe tuck loops created by the white in this instance have the elongated slip stitches in the alternate color (blue) partially covering them, creating the darker geometric shape in the top detail photo. The blue is thinner than the white, the effect will vary depending on yarn weight and tension used for the main bed yarn. One can begin to observe the change in width in areas with more stitches tucking. 

If the aim is to have a tighter, more clearly defined diamond, after the swatches rested, the swatch that began in slip stitch setting appeared to “work” better to my eye, even with the single color geometric shape on both sides taken into account. Ultimately the choice is a personal one. The wider vertical stripes created in the white yarn in the slip combination fabric happen because of the 2 stitch wide repeat on the top bed as opposed to a single needle one in a true fisherman knit. Because of the slip setting the results will be narrower in width from it as well.

Ayab knitters will need to program any repeat across the width of the intended number of stitches, and use the single setting. Electronic knitters can enlarge the background pattern field easily, or create brickwork, extended repeats.

Arah-paint offers a free program that allows drawing repeats in different orientations with a few mouse clicks. Shifting this pattern must also be in pairs of pixels/black squares in this instance because of the 2X4 stitch background unit. The 21 (half) pixel shift shows an error in its continuity 22 stitch shift results in a “correct” all over repeat

Quite some time ago I experimented with shadow knits including in posts

2013: DIY design2017 crochet

It occurred to me the same design might work in a tuck rib version. The original repeat was 24 stitches wide, 28 rows highscaled to double length, 24 stitches wide by 56 rows higha tile test of new pattern Knit tests: the red yarn was a very strong cotton, hard to knit smoothly, the blue encountered some stitches not being picked up on the main bed as well, but the concept may be worth exploring further. The main bed is set to tuck in both directions, the ribber to knit throughout. The red and white fabric is considerably wider because of the tension required to get the red cotton to knit. Better stitch formation results with the different yarn used for the second color

And lastly, a first quick adaptation of a design previously used for drop stitch lace, which requires some further clean up the yellow squares indicate loops tucking on both beds at the same time, the repeat on the far right is the one tested after eliminating those problem areas. It is 14 stitches wide by 80 rows highan “improved” version, the choice remaining as to whether to make all the blue shapes pointed at top and bottom or “flat” this is my repeat, tiled. It is 14 stitches by 84 rows

2 color ribbed brioche stitch on Brother knitting machine 1

After a complicated nearly 3 months I am returning to some knitting, and am sharing some of my results once again.

I have always found 2 or more color patterned brioche stitches executed in hand knitting as inspiring and complex challenges to admire, but am not tempted to actually attempt to execute them in any way.

I have not knit on a Studio KM in more than a decade. I have been asked whether this fabric is possible to produce on Studio/Knitmaster. The most crucial difference imo between the 2 brands (Passap has its own universe) is the fact that Studio selects and knits with each pass. Needle pre selection for clues is not an option. I have gathered some information from manuals on tuck knitting including “English rib and Double English rib” as clues to anyone who wants to work out the technique sorting out their own Studio settings tuck on studio km

This was my first Brother machine knit swatch result:

Each of the 2 colors tucks for 2 rows and in turn knits for 2 rows alternately. Settings are changed manually as shown below after every 2 rows knit, following each color change on the left. Making things a little easier: the top bed may be programmed on any machine, including punchcard models to avoid cam button changes in the knit carriage every 2 rows. With the main bed set to tuck <– —> throughout, black squares will knit for 2 rows, white squares will tuck. First preselection row is toward the color changer. When no needles are selected on the top bed (white squares), ribber is set to knit. Top bed will tuck every needle.

When needles are selected on the top bed (black squares), the ribber is set to tuck in both directions. The ribber will tuck on every needle.

Proof of concept: blue yarn is used on rows where main bed needles are selected (black squares). The crossed stitches at the top right begin to represent an effort to create surface shapes or designs on the fabric. They are created by cabling 1X1, making certain the stitch creating the “shape” is carried to the front side of the fabric, the opposite stitch crossed so it is facing the knitter.I used KCI in this instance, first needle on left in work on ribber bed, last needle on right in work on top bed. A border is created on the knit’s edges on the far right and left. The reverse side of the fabric:

Using a blank square on a knit row to help track 1X1 transfer patternsWorking the 24 stitch repeat using KCI; both first and last needles in work on the ribber bed. Due to operator error and forgetting to change ribber settings after transfer row, I chose to stop knitting rather than attempt a pattern correction

Another attempt at cabling, 1X1 and 2X2. That white line in the bottom image on the right was caused by the color changer picking up and knitting both colors for part of the row before my noticing it. I got rid of the “wrong” color from the feeder and continued on. The wider 2X2 cables require “special handling” and eyelets are formed on columns aside them after transfers are made. Before attempting to knit crossed stitches such as the above in an every needle rib, it is worth exploring cables crossed in vertical stripe color patterns single bed. This is a hand knit inspiration series of patterns, better left to hand knitting

one of my ancient machine knit demo swatches:

On any knitting machine with every other punched hole, black squares or pixels locked on a single row, id the pattern is knit in FI, continuous columns of  vertical color are created. 

If the the goal in creating the continuous an unbroken vertical stripe 2 color pattern, one must place like color on like color. Because FI is essentially a slip stitch the fabric will be tighter, narrower and shorter than that produced knitting either yarn in stocking stitch. Cables on the machine need to be transferred across fixed widths between needles, so there are distinct limits as to how far stitches will allow their movement in groups in either direction. Loosening the tension can often help. Sometimes it is possible to create extra slack by a variety of means, making moving the stitches easier. I have found my own limit for this fabric was working with a 2X2 cross (it is possible to work moving single needles as well). Adding to the complexity single bed: proper needle selection for the next row knit needs to be restored prior to knitting it when using the FI setting, movement of stitches is mirrored on the knit side in the opposite direction of that viewed on the purl. Visualizing some possibilities as worked on the purl sideto consider the knit side appearance mirroring is not enough the direction and appearance of the crossed stitches on the knit surface is reversed from that on the purl as well 

When working every needle rib it will take 4 rows of knitting with 2 color changes to produce the striping. R represents stitches on the ribber, K the stitches on the knit bed

Tuck stitches widen the fabric. As a result, the tucked knitting in this chart on the ribber (represented by the color yellow), forces the space between the knit stitches produced on the main bed (represented by the color green) apart, while stitches tucked on the ribber will create the gap between the stitches knit on the ribber, appearing on the reverse side of the fabric. The combinations create the appearance of single stitch vertical stripes.

This is an illustration of one possibility for programming reminders for tracking location of cable crossings 

Every needle ribs are generally knit at tighter tensions than when the same yarn is knit single bed. Too loose a tension in any tuck fabric causes problems with loops forming or knitting off properly, too tight will produce stitches that do not knit off properly. One limitation of crossing stitches here is the actual stitch size, which needs to be constrained to produce the fabric. Tiny stitches need to travel across fixed space. One by one crossing is manageable, 2 by 2 requires extra slack to make the transfers possible.

Adding some “give” to crossed stitches
1: the carriage has moved from left to right after the color change. All needles except for the four white squares in my design were preselected prior to the next row of knit. The carriage now stays on the right
2: take note of the white tuck loops formed on the ribber on the previous pass from left to right
3: white tuck loops ( I chose center 3) are lifted up and off their respective needles and allowed to drop between the beds. This will allow the 4 white cable crossing stitches to have more slack. 
4: cross your cable in the intended direction
5: push cable stitch needles out to E
Knit from right to left, change color, continue in pattern 

With some planning on longer pattern repeats it is possible to plan added clues to tracking rows on which the cables occur, and their location on the needle bed. Repeats with very few marked areas merit testing in tile as any other repeat. The repeat on the left when tiled shows the area of a patterning error, on the right with the missing blank rows added the problem is shown to be resolved.A proof of concept swatch:Planning for all over brick layout of corrected repeat: More detailed charts of the 2 repeats, suitable for punchcard machines, editable further for use in electronics. Ayab knitters need to repeat the final motif across the width of the download to match the number of pixels to the number of stitches in use across the needle bed, use single setting.
