A collection of geometric design blocks built with squares, rectangles, and lines

I have grown fond of playing with ArahPaint’s functions: guess weave from grid, and drawing in repeat, and am constantly amused by the speed with which most design repeats and color separations can now be drafted when compared to the very first efforts in the days of anyone trying to use Excel spreadsheets to accomplish the same tasks.
Drafts designed for handweaving provide endless inspiration for knit design.
In conjunction with ArahPaint, Gimp remains a frequent go-to as well, along with Numbers for Mac for when spreadsheet tables meet charting or design needs.
The programs are free, there is no need to purchase expensive design programs in order to develop DIY motifs.
Developing tiled repeats suitable for multiple stitch types, including tuck , offered some repeats that began with geometric blocks built with squares, rectangles, and lines, some of which are suitable for punchcard knitting.
Many are included here again to serve as a cumulative collection of possible springboards for use as is or for developing more personal variations.
A reminder: the pngs below were saved as indexed, B/W files.
When downloaded, they may be converted automatically to RGB mode.
Prior to downloading any to machines, check their image mode, and if it is RGB, convert it back to B/W indexed. The pixel dimensions text for designs suitable for punchcard machines are highlighted in a different color.
More repeats are available in the post on Working with diagonal patterning in machine knitting
Larger pngs may be subdivided to change their appearance or alignment of specified numbers of cells.
To begin with, cells may be filled in any color, with mode and color changes to indexed BW if for electronic download

35X35 68X68 A visit to a quilting blog led to these explorations, beginning with a 20X20 repeat, rotated in 4 directions to be combined in new 40X40 repeats for different movements. A first simple 40X40 grouping tiled X5 in width and height, also color reversed to visualize the result with the potential exchange of the yarn positions in the color-changing sequences Dividing the repeat in half, color inverting the 20X20 segment on the right, combining it with the left half And with color inverted quarter segments In the following designs, the meeting points are slightly offset. and lastly, aiming for more of a diagonal Varying shapes
