To mesh or not to mesh 6: chevrons

While creating the test swatches for a version of single bed 3D scales using the lace carriage I was intrigued by the chevron effect that became more obvious with color changes The fabric was capable of changing considerably in look and width that could be encouraged to remain more permanent with blocking. There is a visible asymmetry, with one side of the chevron actually containing an extra eyelet. Still trying to retain the 24 stitches in width design constraint, I began to work with simply counting eyelet transfers matching in number, guessing rather than planning. Tiling the repeats can help get a sense of how things line up horizontally and vertically. Electronic repeats can be minimal unless one is programming the pattern as a single motif that includes edge knit stitches etc when downloading via cable to an electronic or using Ayab interface.A and B continue to produce uneven numbers of eyelets on each half of the resulting “V” shapes. The greater the number row repeats of eyelets in a single direction, the more the resulting bias. If asymmetry is the goal, then this may meet the need. I knit most of the swatches on 48 stitches, with more needles added on the right if needed to ensure the edge stitch will be a knit one. Larger shapes require wider tests. The photo is rotated to reduce its length on the page This effort produced uneven sides of the Vs, and the eyelets along one of the vertical center column were not properly formed, resulting in an added knit stitch The added eyelets in pattern C produce an interesting change from a sort of V shape to more of a W, but the fabric is still unbalanced Back to the drawing board: a different mesh, with eyelets in alternating numbers, resulting in a  more balanced fabric. Here the charted repeat is shown X2, side by side.Different day, same yarns, both were having none of it. When knitting progresses in this manner, it’s a good time for the machine and its operator to practice social distancing.  The quality of the lines produced by the mesh was different and heavier than the one I was seeking, though the number of eyelets remained constant on both sides of the center stitches, alternating on the alternate pairs of design rows. Back to charting things out in Numbers: though the LC, usually (but not always) starts located on the left, preselects on its first pass to the right, and begins to transfer to the left on its second pass back to the left, in order to visualize the direction,  the repeat is mirrored. Cyan cells indicate transfers to the left, magenta transfers to the right. This 24 stitch repeat shows where 2 transfers wind up on a single needle while an extra knit stitch is also formed in the blank vertical column, seen in swatch above. In programming an electronic KM the black pixels alone with 2 blank rows above the second set of transfers is enough. I like to program repeats that are a bit larger, and usually will tile them as well, looking for any errors my eye might notice before any actual knitting Using electronics one may expand or reduce the number of stitches in the repeat to reach an estimated equal number of eyelets With any mesh, the number of knit rows may be varied between each pair of transfers. My swatch was knit using a 26 stitch repeat widthThe cast on used is a temporary one. In final pieces, the quality of any bind off and cast on should be tested as well to accommodate the changes in width lace fabrics may have, increasing exponentially on the number of total eyelets. The knitting this time went smoothly. The eyelet count was as planned. That said, I was 6 stitches away from completing the bind off when the yarn simply ran away from me and chose not to make any effort at rehanging the piece. In the top blue stripe, the number of knit rows between transfers was increased from 2 to 4, while in the top white stripe I alternated between 4 and 2 rows of knitting. Playing with such intervals between transfer rows of transfers can produce interesting differences and perhaps a more static quality in the fabric after blocking the completed item. The knit carriage is set to N, so it has no effect on the advancement of the programmed lace pattern.
As often can happen in machine knitting, another day, same yarns, same tension, same operator and stitches drop, get hung up on gatepegs, and perform other unwanted actions. My next test aimed for that “W” shape. I downloaded an image that accounted for all needles in use for my swatch, so in the 930 using the isolation button on by default with img2track was OK. Your machine may vary as to which side of center the extra stitch will be placed when the total number of stitches in width is an odd one. If uncertain, plan the repeat for the next even number, in this case, 52, divide it evenly on each side, and either air knit to sort out selections before casting on or simply transfer that extra knit stitch over one as you begin to knit. In a final piece, good notes will provide reminders for such small details The blue yarn refused to knit off properly, so the added colors were tried to see if I fared any better using them. My first swath was discarded, the second one is shown. The repeat is sound, the visible “errors” are the result of stitch formation issues. The swatch stretched in length that could be set with blocking has a very different look when lightly touched with my now fiber burning iron Different day, all other things being equal, same needle locations resulted in easy success. I programmed for a 60 X 24 repeat, planning for different size Vs.During knitting, these fabrics will appear to be producing straight color stripesIt takes a while for the change to begin to be noticeable This was the result as the work came off the machine, relaxed, with no treatment of any sort the ribber is in place there are avid beliefs expressed by folks in terms of whether or not to bring the knitting to the front of the ribber, I am a between the beds’ advocate. Also, even with the ribber off my machines have always been set up with ribber table clamps in place since having them flat simply never worked as well for me in any of my knitting.A one-color zig-zag from a Brother punchcard pattern book with a different approach, that could serve as trim or form an accessory. There are limitations in producible width. The stretch of the cast on and bind off and the fact they need to match as closely as possible while allowing the mesh to stretch sideways in blocking must be taken into consideration, as is the fact that every end needle selection will occur regularly and those selected end needles must be pushed back consistently. There is no way to avoid that on a punchcard machine, in electronics one could again program the width and add blank pixel column on each side. Here the cast on was using waste yarn and continuing in the pattern, the manual end needle canceling of selection was inconsistent at the sides, and LTBO (latch tool bind off) around single gate pegs was simply not stretchy enough. Here the cast on and bind off match very closely. I used the looser cast-on method described by the “answer lady” in the video, but I bound off around 2 gate pegs instead rather than wrapping the needles as shown, a method often used on the PassapMore information: a hand transfer striped lace variant 2014/03/27/striping-in-lace-fabrics-1/, and another using a stock punchcard 2013/07/26/from-lace-chart-to-punchcard-3-adding-stripes/

Single bed scales made with stitch transfers


In the past, I have explored several ways to knit scale-like fabrics aka dragon teeth/scales, and a multitude of other names. My test swatches were created using racking, pattern repeats were provided for both punchcard and electronic machines. Some of the archived material:

With summer here and a long absence from lace knitting, I was curious about producing scaly fabrics single bed. Lace transfers may be used to create folding fabrics with permanent pleats, so what about 3D shapes? I began with a repeat suitable for a punchcard machine and its limitations, adjusting it in 3 different ways A variation of Card C, with 2 rows blank after each pair of transfers throughout was used in borders in some of my lace shawls including these, made in 2011.  All 3 card designs share the fact that the lace carriage (LC) makes 4 passes followed by 2 rows using the knit carriage set for normal knit to complete the eyelets with exceptions. The exceptions are in areas where there are extra blank rows, there the lace carriage will make 6 passes in order to reverse the direction of transfers. Brother lace cards usually start with punched holes on the very first row, have 2 blank rows between LC passes that complete one sequence (here each sequence is 2 rows in height), and 2 blank rows at the top of the card.  Lace markings are few and far between, errors are easy to make when punching long cards and working in designings with pixels in particular. In this case, I did not notice until I began composing the post, and after I had completed the first test swatches that the repeat on the left has an extra 4-row segment in the top half, making it 24 stitches X 54 rows as opposed to the other two at 24 X 50.
In any lace patterning if a zig-zag is wanted in parts of the design, having 3 blank rows in planned locations will reverse the direction of the transfers from those below them. Blank squares in rows containing no punched holes (or pixels) will have no transfers, so in their absence stitches in those areas will be knit, producing extra stocking stitch rows. The spacing for such knit areas on the card may be adjusted to suit. This segment of the above designs identifies the areas in both rows and columns with no punched holes (or pixels)The knit side of the fabric is the most interesting. The swatches were at first photographed as they were immediately after their removal from the knitting machine. I also tried to photograph them at an angle to show the protrusions from the surface. Pattern A:A short test version using cards B, and CWhen using card A, the shapes alternate vertically between all mesh ones with all knit rows at the outer edge of the folds. Using Card B, all protrusions have a fixed number of knit stitch rows at the outer fold. Card C produces an all mesh fabric that made me think of ocean waves somehow. Turned sideways, and pressed to set the folds, the resulting fabric could provide a springboard for a host of other, different ideas: A larger swatch started on waste yarn, with 2 rows of knitting at the bottom and at the top before binding off. The design is card B, with 4 rows added to each half of the design. I am still working with the constraints of a punchcard machine, and for the moment, of retaining symmetry in the width of the “scales”. The working chart, turned counterclockwise to save space Planning for 3 repeats based on 24 stitch widths the above arrangement will, in turn, need to be mirrored for the lace pattern.My sample was knit using 2/15 wool at tension 7, using needles 36 left to 35 right The actions reviewed once more
The knitting in progressI cast on loosely enough, but the bind off was too tight at the top, which should always be tested on swatches before committing to a project. The resulting fabric was photographed immediately as it was removed from the machine. I tried to touch the edges only with an iron, and mine is now overheating and doing a good job of burning my wool, thus the color changes in spots With an attempt at some steaming and pressing, the folds are retained Often the question of what fine lace is and how it is made comes up. Fine lace is a fabric against which I have a personal bias. It seems to involve a lot of work for the result unless one is using a light-colored yarn with a smooth surface to show the subtle and at times hard to observe surface changes. It fares better visually when mixed with eyelets. The yarn is shared between the needle that would normally be left empty and the one with the formed stitch already on it to its right or left depending on the direction of the transfer. If the shared yarn is dropped instead of staying in the hook of the transfer needle, as the next 2 rows are knit there will be eyelets on the ground lacking them anywhere else. Card C, knit using only the fine lace setting on the LC, looking very different from the previous fabrics, both knit and purl sides are shown, with a couple of spots where the yarn was not shared by 2 adjacent needles, forming eyeletsNow evaluating the possibility of mimicking my hand-knit version:Planning out a repeat in chart form:Knitting began with working in a 2/15 wool, tension 6, using a 7 prong tool with all prongs engaged to transfer groups of stitches onto their new positions on the needle bed. The first two images review picking up from the row below to fill in needles emptied by transfers. It is one of the machine-knit equivalents for the M1 direction in hand-knitting patterns. As a result, the number of stitches being knit remains constant throughout the pieceThe stitch structure so far appeared too loose to me, so I then switched to a 2/8 wool, at tension 7 with the intent to test knitting as tightly as possible while still facilitating the multiple moves of stitch groups on each row. The resulting fabric was stiff and wanted to curl strongly to the purl side, needed pins to help it lie flatter. The shapes refused to stay poked out to the knit side.
I seldom wash my swatches, viewing them simply as proof of concept of technique concepts, not usually as springboards for finished pieces. Generally, I stop at steaming or ironing if needed.
When I made garments for sale in wool I usually tested the swatches and washed the finished garments as well. The “hand” and the behavior of the finished piece can change considerably. The hand-washed sample in the second illustration below lies flat, has a soft, drapey feel absent in the unwashed, retains the flatter shape with no encouragement needed. In its 2/15 portion, the “scales” became more flattened as well.
Washing wool removes any sizing and excess dye. Open spaces in the knitting become reduced in fulling, as opposed to closing tightly in felting. Using a constant temperature in both the wash and rinse and avoiding excessive friction, in turn, avoids excess shrinkage. On electronic machines, one does not have the limitations in terms of the width of the repeat maxing out at 24. For example, the number of eyelets on either side of the block components of the repeats may differ, the greater the number of eyelets, the wider the spacing between the 3D shapes. Gradations may be planned in height and width of repeat blocks across the full needle bed, limited only by patience in designing, the capacity to download, and the tolerance for both the yarn and the operator to complete wide, long pieces using the technique.

Experimentation can yield quick results, sometimes with unexpected but pleasant surprises. One of my best selling felted items for a couple of decades was an accessory that was planned deliberately to mimic a test piece that had almost been tossed in the trash. It’s good to return to things after a break for another look, and then it is really helpful if notes were kept. Another variation of the A-C cards in single repeat was tested at the bottom of the swatch belowand in a staggered one, tested at the top of the swatchThe “scales” were more like twisty bumps, with subtle variations vertically in some of the stitch groups. That said the results were dramatically different when color changes were added to the pattern knitting in the shorter repeat. Blocking may make an even more marked difference depending on whether the mesh (lightly steamed) or the tighter knit (vertically pulled, should be washed) produces the preferred effect. The looser stitches at the top outside edge ie at the top left corner are the result of a stitch that got away from me. The cast on was a bit too loose, I knit 4 rows at the bottom after the cast on and 4 rows at the top of the repeat before binding off.The differences in the width in the same fabric are dramatic. Any overall mesh/ lace fabric blocked for openness such as on the left will grow in length over time, is best stored flat, and will benefit from episodic pressing/ steaming to reset the width. Then I began counting eyelets, which were equal in number in the schematic for the repeat, but not equal in number on either side of the center pivot for the bend in the herringbone shape when the piece was finished. Any extra eyelet rows in the same direction will result in increased biasing in those sections. Time to test more mesh variations, a topic for another day.

Machine knit leaves using slip stitch with holding

In 2012 I had a sort of leaf obsession, which led to my exploring a range of shapes created in both hand and machine knitting, including a series of shawls that were machine knit, using the lace carriage, intended for both gifts and sale.
Online resources were not as abundant back then, searches are more productive now via browser searches, pinboards, and Ravelry.
I have always been interested in holding techniques and automating them on both punchcard and electronic machines. In recently revisiting shell shapes I was reminded of leaves once more and thought I would return to working with them.
An early abandoned effort in trying to construct leaf shapes automating their shaping using holding in combination with slip stitch followed other earlier posts is shown below. In all honesty, I have been blogging long enough so I often do not recall previous writings on a recent spark of interest and execute a personal version of reinventing the wheel, starting from scratch, or executed poor note-keeping which in turn requires it.
A variety of lozenge and “leaf”-shaped forms may be found in previous posts on holding intarsia, some are strictly hand-selected, others are automated. There is a series of 5:

Checking the repeat for a single shapeAdding a second color and reversing directions of shapes brings lots of yarn ends and its “price to pay”Some handknit large scale inspiration to begin my revisit to MKing them: Garnstudio 1 and Garnstudio 2, which introduces lace transfer stripes between leaf formsA free hand knitting pattern, “Papagena“, that takes similar shapes to a triangular layout for shawl shaping Stitch Maps is an online source for hand knitters with interesting graphics that include some for held shapes, such as this The chart is actually rotated 90 degrees counterclockwise, could serve as inspiration for an electronic pattern.

Returning to a possible far smaller repeat that may be executable on a  punchcard machine as well. The central vein in the forms is created by having held stitches with no wraps along and up to its center in height, creating 2 continuous shapes that mirror horizontally and repeatAutomated holding sequences may be planned for single or multiple stitches in width, as well as for single and multiple rows in height. For the new initial test, which proved to need editing, this was my repeatA tiny test in too thin a yarnI am knitting on a 930, the image needs to be mirrored in order for it to appear in the direction I intend on the knit side. The above repeat did not work properly when knitting a whole row of shapes. With some patience, a final, edited, and mirrored repeat was developed that enabled a completed a full row of shapes using the slip setting and holding, and starting with working it from right to left. Sometimes differences are subtle, especially in designing using single-pixel units. The new repeat proved to also work for rows of shapes in the reverse direction after horizontal mirroring and restarting the pattern or design row 1. When working from right to left, the initial preselection row is from left to right, while when working from left to right, the first preselection row is from right to left. After a full row of repeats is completed, the pattern is rolled back to row 1 and mirrored. Punchcard knitters could turn the card over and start again on the proper row. I used contrast color knit rows initially in between rows of shapes to help me note transitions more clearly. The “leaf” is not pointy enough for me, but at times what was not planned may lead to a pleasing result of a different sort.
The amended, corrected repeat is shown on the right To knit: cast on with a multiple of 12 stitches on each side of the center 24 on the needle bed
Cancel end needle selection
COL: first preselection row from left to right
COR: set machine for both slip <– –> and hold
all needles will have been preselected, knitting every stitch, knit 2 rows, return to the right, as the row is knit, patterned preselection occurs
COR: bring all needles to the left of the first 12 on the right into hold position, knit until all needles in the group of 12 are preselected again, the carriage will be on the right
*COR: bring a group of 6 needles to the left of the 12 stitch group just completed into work, knit one row to left
COL: bring 6 stitches from the completed shape on the right to hold, continue in the pattern on the new  12 stitch group until all 12 stitches are once again preselected, stopping with COR***
repeat * to *** end working the full last group of 12 stitches on the left, including the last 12 stitch preselection

At the completion of a row of shapes COL: make a decision about the transition, whether any extra rows knit are a problem or not, and whether added rows in contrasting colors are wanted. To proceed with no changes in cam settings and 4 rows of knitting between the rows of shapes remembering that the first preselection row needs to be made from right to left.
COL: manually return all needles to upper work position (D). They will knit row 1 of the stripe
COR: manually push all needles to D again, return program to design row one, check settings, as the first design row pattern is preselected an all knit row 2 will be added. As patterning resumes from the left another 2 all knit rows will be produced before selective patterning occurs.
If any extra all knit rows are wanted cancel patterning on the knit carriage, set it to N, knit the extra rows, remember to end on the proper side for the first preselection row, and what options may be necessary to complete that row correctly.
To reverse patterns without extra knit rows:
COL: store yarn.  The carriage can be removed and brought to the opposite side, or stitches need to be manually be placed in the B position for a free pass to the right. This involves placing the cam selector button on N, returning the cams set to slip in both directions.
COR, all needles also need to be in work in B position, no yarn, in order to make a free pass to preselect from right to left, ending COL
COL: pick up yarn and continue in pattern. These textures require a lot of carriage passes, which tend to fuzz up the yarn on the purl side of the knit a bit. The shape I created was not very leafy to my mind, but still interesting, especially on the purl side. The yarn used in a 2/15 wool, knit on Tension 5Moving on to a wider version, using 24 stitches in width to allow for using the pattern on a punchcard: this repeats works both as-is and mirrored, the groups of stitches moved in and out of work is now half of the new design repeat = 12. Making the repeat work in any number for this shape involves lining up the needle selection in each group of needles and constant counts for holding sequences. Punchard knitters would need 2 separate cards. The lovely mess in the swatch happened when I stopped paying attention to everything but what was happening on the needle bed and missed the tangle of yarns in my yarn mast. There is enough knitting however,  to note that the repeat is sound and that the edges on both sides are formed by the narrowest part of the shapes in each direction. One way to solve that is by casting on and binding off along tops and bottoms of shapes as seen in the yellow and green swatch at the top of the post.Planning things out to release those edges as seen at the top of the post

Working on outlining the shapes with contrast color:Problems to solve: maintaining an even number of rows in-between shapes and a straight edge along both sides. The latter could happen with triangles prior to knitting full shapes at either or both ends, the first sample failed on the left side due to both triangles being knit in the same sequence;   that may be solved by beginning shaping on 2 stitches on the left rather than the full 12, mirrored. The proper sequence for actual knit stitches for the first, bottom set, and mirrored for the second, top set still only partway there I am presently knitting with my left hand in a splint that has exposed velcro teeth, which has caused some interesting issues with actual knitting and with yarn snags. To end this latest effort, in yet another knitting aaargh! moment, it appears my iron is now overheating and burned the wool! From observing the above swatch on the purl side it looks as though each row of shapes needs to have a triangular shape at each end. Also, the contrasting color line thickness is not constant. The purpose of automation should be to make things easier, not confounding. After yet another trial, I decided to give up on attempting to use the automated repeat to produce an effect that was consistent and made me happy.

Setup for a leaf in each color is far less fiddly and simpler to execute. A tentative layout and knitting sequence:
Begin on waste yarn, decide on the color of the cast on, and any additional knit rows prior to beginning in the pattern. Each of the side triangles is shaped using manual holding techniques over 12 stitches. If starting on the right, the first preselection row needs to be made moving from left to right as above on the first 24 stitches. With knit carriage set to both slip in both directions and holding with COL make certain the first 24 stitches on the right in B position make a free pass to the right.
COR: cut yarn, change color, knit the first shape repeat, end COR
COR: when all needles in the group are preselected, push first 12 needles on the carriage side out to holding position, push 12 stitches on their left back into upper work position as you would in any holding pattern, they will knit in the slip setting as well. Cut the yarn, change color, repeat across the row of shapes
COR: when the last group of 12 needles on the left is preselected with all needles out to hold or removing the carriage and positioning it on the other side, begin knitting COL.
COL: manually knit triangle at top of the previous row of shapes
If a contrasting color stripe or any other pattern is intended between a full row of shapes, execute them and end COL
COL: shape the second triangle for the start of the reversed row of shapes, get the carriage to the right side by a pass over all needles in holding position or removing the carriage and bringing it to the opposite side
COR: the second pattern is programmed. Punchcard knitters use the second card, electronics mirror the shape. With the first 24 stitches on the left in B position and the knit carriage set for holding and to slip in both directions, make a preselection pass to left.
COL: change color, knit shape and continue on as described above reversing shaping
As with intarsia, there will be lots of yarn ends to weave in and clean up those eyelets at the start of each color change. The swatch after a quick pressing

The possibilities could be endless.  Electronic machines do not have the limitation of working within the 24 stitch maximum design width. Shapes can be fully automated using only slip stitch setting, no holding, but repeats become exponentially wide and long. The technique merits its own post.
