A good online grouping of mesh repeats is one place to start exploring this topic. Most proprietary large pattern books from machine knitting companies include at least a few suitable cards/mylar samples. They can be used for “all over” fabrics, borders, striping in mixed bands of varying styles, etc. I am presently interested in pursuing filet crochet-like structure by superimposing knit areas onto lace mesh using “low tech” punchcards or mylar sheets. Filet crochet is often built on a system of solid squares on the more open “ground”. Emulating this type, to begin with, here is a punchcard for use on Brother KM resulting in a “square mesh”
a lazy way to explore how adding solid areas to any pattern card is to mask a portion of the card using tape ie. in this case painter’s tape on the reverse side; this is not the best long term solution, but OK for “testing the waters” and sorting out the final repeats. Here is the resulting card reverse side
the card was extended for a full, alternating blocks repeat: the first run at a swatch result showed that oops! I am not quite there with alternating blocks of 4: no worries, more tape is on hand. Below is my preferred, sideways view of the present fabric. There is a difference in ridges/ lines as viewed horizontally, every other is thicker because of the location of transferred stitches. Knitting sequence is 4 rows of transfers with lace carriage, followed by 2 rows knit with KH throughout. A good starting point.
