WORK IN PROGRESS
I still surf Pinterest daily and often encounter published punchcard repeats that catch my eye.
Many need some interpretation and editing for use in specific machine models.
The first inspiration: is knit using 4 colors, alternating 2 rows of a base color, then rotating color changes for 4 rows for each of 3 contrasting ones.
Counting up from the bottom of the illustration after the marks for the typical two all-punched rows, it would appear this is a Studio punchcard, but starting row 1 as read outside the card reader can simply be changed for any other brand knitting machine.
The every other row configuration below is for an every other needle repeat used in early machines such as the Juki.
A full reference volume An illustration of the card use If one is using thicker yarns on a standard that grinds at the loosest tension, this configuration can retain the full design while knitting EON.
I began adapting the design using Mac Numbers, the repeat was isolated and traced, and the 12 blank columns were then hidden producing a result scaled in indexed B/W mode to 12X36 pixels and saved. The tiled design, checking alignments. The proof of concept Periodically tuck stitch designs that appear to break the usual rules for the stitch are discussed.
This design is intended for a push-button machine capable of 24 stitch repeats, uses symbols in the associated chart, is interpreted to mean tuck loops form for 2 rows and knit along with all other stitches every third row. The working repeat is made up of 8 pixels in width, and 36 pixels in height. This next design is likely published for use with the Studio color changer, which is marked with letters for each color, rather than with numbers as in Brother models.
It is intended for a slip-stitch knit. The bottom swatch relies on color changes every 3 rows, which would need to be performed manually. In the elongated version, colors are changed every 6 rows.
The design was tested knit in thin yarns using the electronic 24X84 elongated PNG tested for alignment and displays interesting 3D variations, the purl side is remindful of shadow pleating Changing colors every odd number of rows is a tad fiddly.
The use of the color changer is not an option.
With the three yarns fed through the yarn masts, it became hard to keep them from twisting around each other. Ultimately, that problem was solved by hand-feeding one of the three colors with the cone on the floor, in front of the machine, as one would place yarns for weaving.
Brother knitters are familiar with yarn placements in the sinker plate. Position A is for knitting when using only one color or for the ground color in fair isle patterning. There is a “gate”, which is closed, and the B color/contrast motif color is placed in that front position, knitting the yarn in needles preselected to needle position D on the next carriage pass.
It is tempting to leave the gate open when switching colors by hand frequently, and that may work for a while, providing tension is placed on the yarn manually to keep the yarn back.
If at any point the yarn shifts forward (green arrow), with no needles in position D, stitches will be dropped.
Textured stitches are more complicated to rehang and correct errors.
Taking the extra seconds to close the gate (red markings) after each color change avoids what became fondly known as “dropitis” in my classes. The proof of concept: two of the yarns used were acrylic, so steaming to reduce the curling of the swatch flattened the texture a little. Converting random transfer lace designs poses different challenges, and since the time at which the reference post was published, there have been several Gimp updates.
Lace designs contain few black and white pixels and, at times are brand-specific. Multiple transfer lace in Studio models begins with 2 blank rows, while Brother begins with a design row, and ends with 2 blank rows. As given, the inspiration repeat is designed for Studio/Silver Reed.
When using any program, ie Gimp, ArahPaint, or even Dak, the original scanned or screengrabbed design needs to be aligned horizontally and vertically to window borders for accurate conversions.
Before any scaling of images, establish stitch and row counts. In this case, they are published as being 16 stitches X 96 rows.
The process for converting the same lace design using Gimp 2.10.34 on the Mac, beginning work in RGB mode:
1. drawing a straight line to the side of the cropped image reveals a slight lean to the right
2. using Image, Transform, and Arbitrary Rotation -0.30 improves the alignment 3. using the rectangle tool, crop to the borders of the published image.
In this instance, the cropped image measuring 199X938 pixels is at first scaled to multiples of 10 for both width and height, note the broken chain link
4. 160X960 pixels. 5. Image mode is changed to B/W indexed, and the image is scaled once more to 16X96, the size of the expected repeat, note the intact chain link 6. the final repeat, when studied, matches that from the results in the previous post 1: the result using ArahPaints tools, including its guess weave from grid, compared to
2: the Gimp final image and
3. borrowed from the previous post illustrating other considerations prior to actual knitting,
if using the repeat on Brother machines, the first 2 blank rows of the design are shifted to the top.
The 16-stitch design width makes it suitable only for electronic models.
The final PNG is actually downloaded as a fair isle pattern while maintaining the required needle selection for lace, and the knit carriage remains set to knit throughout while the lace carriage selects and transfers.
The machine, depending on the model, may by default mirror the result vertically, so the final PNG can be mirrored and saved as here, prior to knitting on the 930, or the mirror function in the machine may be used after programming.
I prefer to save my files in the orientation required for the actual knitting as a means to avoid confusion or errors.
Working in Arahpaint, rotating an image turns it on its center point. To rotate a layer, selection, or image, from the Image menu, choose Rotate. Selections can be made at offered angles, or specified degrees can be entered in the degree field, or select an area, move the pointer outside the bounding border, and then drag on any one of the small boxes at each corner while pressing the left mouse button. To align the image,
1. load the lace inspiration
2. choose Image, select Rotate Image, and draw a line that follows the orientation of the image. The color will be based automatically on the palette being used, and altering the pencil pixel size or color has no effect.
The program then rotates the image and will inform you of the rotation angle, and the drawn line becomes straight.
To confirm alignment, click the OK or Close button in the Rotate Image window.
3. use the rectangle tool to select the content for the full design repeat, and crop the aligned image to the selection. 4.-9. continue with the steps using the tool Guess Weave from Grid, producing the same final PNG. In summary, they are:
4. crop the selected image to size
5. change the color palette to 8-bit, adjust background and foreground colors
6. reduce the number of colors to B/W, adjust the threshold, and set the number of colors to 2
7. the resulting image
8. use the guess weave from grid tool, crop the bounded image to the selection, magnify the results to visually check the repeat, and save the PNG if satisfied
9. the final 16X96 pattern repeat, matching the Gimp result. The associated swatch
