Gotta admit, I like design challenges. I like them best when they work out, of course. This one did. A friend and member of the Facebook Pin Loom Weaving Support Group asked if I could design a square that looked like the stripes of a flag waving in the wind. After a number of attempts—and several rejected ideas—this is what I arrived at.
The fun part of the challenge was designing softish undulations (as opposed to pointy zigzags) that joined up with each other when placed side by side. (If you want sharper points, just add U3 at the apex or nadir of each V.) This is roughly what the squares would like when joined up into horizontal stripes.
