I tried a few ways to make wallpaper and border/frieze patterns.
One was an asymmetrical stencil (Cara did something similar above with a symmetrical one) traveling along a ruler. I could imagine a variety of asymmetrical shapes cut our of heavy card or vinyl which patrons could color or sponge paint through.
Then I wondered if you had a deck of transparent “cards” (like overhead projector prints: toner on acetate) all with the same fundamental asymmetrical shape that you could lay out and play with the variations in rotation and translation, and see how many different permutations you could get from that shape, that could be cool! Here’s a quick sketch with a very irregular shape which is trying to be the 4-arc shape from the screenshot in Avery’s post.
