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
