I've come up with two options, both in double-face and can be done using the same warp, so you can try both and see which you prefer. The first one has a pattern repeat length of 12 picks/ rows.
You will need to flip the threading direction of 10 of the pattern tablets (6, 8, 10 ,12, 14, 16, 18, 20, 22, 24) before you try the second version of the pattern. The second version of the pattern has a pattern repeat of 24 picks/ rows.
As with all of the free patterns on this site, you are welcome to weave them, sell bands woven using them, and use them to teach other weavers, just as long as you state where you found them.
