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 shape
Adding 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 forms
A 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 repeat
Automated 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 repeat
A tiny test in too thin a yarn
I 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 5
Moving 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 the 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 stitches 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.


The 910 in my default setting produced the “image’ as drawn on the knit side of the resulting fabric. The post was written prior to my tiling the repeats as a matter of routine to check their alignments. Doing so would have shown a couple of missing pixels, and pointed to any other errors in filling in mylar squares.
All transfers were made in the same direction.
As always, ideas need error-proofing and refining, easier done in a chart if possible prior to any actual knitting.
There are several changes to make if it is necessary to get the pattern to reverse direction in alternate rows of completed shapes in a brick layout.
Attempts to visualize holding can happen in spreadsheets, documents, image processing canvases, or even simply on graph paper, moving/ “drawing” back and forth across the cells mimicking carriage movements and marking them accordingly.
The 930 automatically mirrors downloaded motifs, if direction matters, as in these samples, either mirror the design horizontally prior to saving the PNG for download to the machine, or use the mirror button selection on the operation panel after the download.








while here the repeat for all full-size shells is planned,
Marking up the needle bed with water-soluble markers or pencils helps track placements of repeats across the desired number of needles in work: dark lines indicate placement beginning with the mark for half a repeat to maintain straight side edges on the finished piece. Red lines mark the placement of the stitches when they are moved to the left to knit the full shells across the bed. 


Scaling the image to render it a bit more legible:
The machine will be set for slip stitch in both directions and holding. End needle selection is canceled.


I used two repeats side by side to eliminate having to consider and choose the position option on the 930 needle bed, resulting in having the pattern centered in each 24-stitch fixed segment of needle selection.
I was too aggressive with clipping yarn ends on the left side, especially while changing colors, not ever a good idea. Automating the pattern fully on electronic models using only slip-stitch patterning is possible. The length of such patterns grows exponentially in proportion to the size of the repeats. Reviewing errors in the beginning concept
An attempt to visualize the placement of the shape variations in the finished piece using the shell motifs beginning with the shapes created in order to create a straight side edge
COR: knit a base row in color one from right to left
Preserving the 3D texture relies on using yarns with “memory”, ie wool and avoiding aggressive blocking. Using thinner yarns makes the stitch formation more evident. Hard pressing, in this case, knit using acrylic yarns, flattens the fabric considerably, and often, permanently. Both the hold/slip (top) and fully automated swatches (bottom) are shown.

When the end of the first row that row is reached, as contrast color is added, stitches need to be cast on on the far left in order to keep the work on the bed a constant number of stitches. The usual method suggested is e wrapping, this is picking up from the row below. I found either method produced looser, longer stitches on the far edge 
reaching the far right: 














It does a good job of weighing down those straight edges along the bumps, making the stitches easier to pick up. When rehanging those stitches, uniformly hanging the loops, not the knots along the edges involved will give a smoother join. Here a paper clip is used as the “hanger”
Lastly, a swatch ending in all knit rows. The only remaining issue is the fact that those side triangles are formed by stitches that are looser than across the rest of the piece. This yarn is thin and a poor choice, but fine for getting the technique down and beginning to understand what happens to stitches, how one needs to move from one side to the other, and what happens along the edges of each individual shape 


to consider the number of stitches required and whether the fact that other than garter stitch knit stitches are not square,








with a touch of steam and light pressing 

This is the isolated repeat for converting the pattern to a file suitable for download
and its mirrored version for knitting from the opposite side
My test swatch was knit on the 930, using img2track. Because not every needle on the bed is in work throughout the knit, end needle selection must be canceled (KC II). The knit carriage after the preselection row is set to slip in both directions. Because only a few rows are knit on the red blocks in the chart, the result is subtle. The white yarn used in many of my tests happens to be a 2/24 acrylic, so on the too thin side, and likely to be well flattened if pressed.
Often, the edge stitches on the carriage side will tend to be a bit tighter than those formed away from it. The same repeat may be used to create very different fabrics. Eliminating the all knit columns on either side of the center produces a piece with “ruffles” on either side of the center as the outer edge of each shape is no longer anchored down. The principle was used in knitting “potato chip” scarves popular in both hand and machine knitting for a while. Having a repeat on one side of an all knit vertical strip creates a ruffled edging. 
Note the effect of the added all knit rows on the “wave” of the piece on the right.
The shapes for the “bumps” may be changed, moving away from rectangular formats. Small repeats are used for the purposes of illustration here, but they, in turn, may be scaled up, rendered asymmetrical, vary in placement, and more. My design steps began with this idea
Following the goal to achieve bilateral placement along a central vertical knit strip, with vertical knit strip borders at either side, here shapes point in the same direction


I ran into an interesting problem for the first time. I had entered the row and stitch counts on my chart, used those counts to scale the image used for my repeat down to size for knitting, kept getting floats where there should not have been any, could not understand what the error in the repeat might be. What was happening is that because of the wrong row number used in scaling, there was an extra pixel row in the first test swatches resulting in knitting errors. The final repeat is 29 stitches wide, 38 rows high. This is the resulting swatch
Once more, the repeat could be reduced down to eliminate side knit strips, or limit shapes to one side only for a one-sided ruffle. What about repeating the same slit horizontally across a row? Repeats become very long, arrows are intended again as guides in the knitting direction.
An even number of rows (green) at the end of the outlined repeat will return the carriage to begin knitting it from the right side once more. An odd number of rows added at its top will prepare for knitting the motifs beginning on the left. 
Pushing unwanted needle groups back to the D position will make them knit rather than being held, which is another way to vary the texture distribution across any single row





The reverse side shows the same issue. Areas can be identified where the held stitches have been hung up to create hems. Note that as the knit grows in length, at the completion of each row of repeats there is one segment with no hem on alternating sides. A longer test swatch follows
I created my hems on the carriage side, immediately prior to bringing the following group of stitches into work opposite it, and knitting a single row across that new group of 3 segments. The highlighted area indicates the stitches to be hung to create the hem. The eyelet on the top, right, will be smaller than the one at the opposite side of the stitches to be hung up








Reversing the direction of segments







This is one of my early graphics trying to imagine what is happening in chart form, which also references the repeat in the Passap garment, followed by plain knitting 

This fabric is worked out differently, in groups of 2. After the first segment is completed, COR if the starting group 1 worked is on the right, bring group 2 into work, knit one row to left, immediately bring group one into hold, and continue across row. That “float” is created as the yarn traveling between the last stitch on the right now coming into hold and the first stitch to its left knits for many more rows gets pulled on as the piece grows. 



Hems in knitting can be created on any number of stitches, anywhere on a garment, by definition join segments of the knit together permanently. Folds are freer. Here is an attempt at a different wisteria cousin with organized repeats. More on creating it will follow in a subsequent post now that holding techniques are back on my radar 
I like to chart out my repeats and plans for executing fabrics, along with ideas for possibly varying them in ways other than suggested, this was my beginning 

knit one more row to return to the opposite side 





I knit 3 rows rather than 2, to return to right side for bind off
here is the swatch, still on comb for “setting stitches”







when the 20 rows are completed the carriages will once again be on the right, all stitches will have been knit on the previous row
transfer all ribber stitches to top bed, knit 2 rows, bind off. None of my swatches were blocked other than by some tugging, particularly along the bottom edge. The spacing between stitches is narrower because ladders created by single needles left out of work are formed by yarn lengths that are shorter than those that happen when stitches are knit and then in turn dropped. The height of the swatch is also affected, and the half fisherman texture in the wool swatch, in particular, is more evident.
When the work is removed from the machine, stretch cast on outwards, then give each “scallop” a really good pull downwards. Steam lightly over the scallops to set them. Variations of the double bed trims may be worked on the single bed as well.






Since the above is seven stitches wide, if punched accordingly it would occupy 21 out of 24 stitch units on a punchcard. As is unless those extra needles on the far right or left are left out of work for ladders or transferred down to the ribber, it would not be suitable for an all-over fabric. It can, however, be used for a trim. If the latter is the intent, only one series of vertical repeats as seen in the chart needs to be punched. The numbers below the image indicate Brother needle tape markings. The Brother needled tape has a center O position marking, with numbers beginning count with one and radiating out marked in groups of 5 in both directions. 

The single-width repeat may be programmed as pixels, on left, or punched holes on right. In electronics a single 8-row repeat is adequate, punchcard knitters repeat 5 times to 40 pattern rows punched.
I prefer starting such designs on a knit row. To do that, the design repeat start may be shifted
Using the trim as the cast on edge for a garment: determine the length required after a technique test. Knit a bit extra and remove on waste yarn, so more may be added or some be unraveled if needed or you wish to change the configuration using it as your cast on. Rehang and cast on later when it is completed. The flared-out portions of the trim will be used to “cast on” the edge of the piece, continuing with some needles out of work. An attempt at a line drawing of the “trim” sideways
Using the curved out edge of the trim, hang half stitches if possible, or one full stitch away from its edge as illustrated below. Knit 4 rows. With a tool pick up all ladder loops created by NOOW (RC 1-4) and hang them on the center empty needle. Knit rows (RC 5, 6), hang ladder loops on still empty needles, knit across all needles, continue with garment



The yarn used is cotton and appears to have a tendency toward biasing on knit rows as seen in the tendency to lean in one direction in the above photos. It has no stretch, so stitches that knit off several tuck loops remain elongated. A look at the structure on the purl side:
For more trims in this family, please see later post
If using the pattern on electronic machines, the needle selection needs to match on the top bed. Depending on the model electronic, the pattern may have to be reversed for accurate needle selection.
When using card 304, tucking happens for 3 rows forming loops that span across needles out of work, then all stitches on needles on rows with numbered markings on blue cells knit for one row. Orange gradient-filled cells represent rows on which tuck loops are being formed on the held single stitches, which in turn grow in length.

the tuck loops still form on the main bed, the ribber is set to knit every needle in both directions.

Translation of symbols used in Knittax patterns.
On the purl side, this creates structures that emulate crocheted shells. My first attempts at trying to knit anything like this were with thin yarn, and I had enough issues to give up for the moment. Things worked out much better when I switched to a sport weight yarn that seemed to like knitting at T 10 for stocking stitch. With NOOW set up, my sample was knit at T 9. Waste yarn and ravel cord are often a good way to start, but not always necessary; the same is true of weight. I began with a crochet cast on, every needle, multiple of 4 st + 2, then dropped the alternate pairs of needles between the first and last 2 pairs of needles in work, pulling the needles back to A position, determining the width of my “shells.”









Variations can include the number of needles in and out of work, yarn choices, etc.
