I decided to try using some more patterns to create strings, and ended up creating a pattern to use. It’s easy, and you can choose to make it simple and light, or more heavily patterned and dark, according to what you need.
I recommend starting with one row of squigglies down the center, and then adding after you fill the sections. That way you’ll know if you want white space or dark.
