In my Etsy shop, www.ASpinnerWeaver.Etsy.com, I sometimes sell my favorite yarn, Omega Sinfonia, in packs containing 4 colors and include a sheet with a dozen possible combinations using those colors.
Below is one of those sets of 12 patterns which I invite you to use for yourself as they are, or as inspiration to create your own designs. These use 39 threads, and for me, when I use them with the Sinfonia, the woven bands come out to about 1" in width. This width is great for dog collars and leashes, hatbands, key fobs, lanyards, ukulele straps, and lots of other things! For a list of suggested uses for woven bands see this page http://aspinnerweaver.blogspot.com/p/uses-for-woven-band.html
All of the patterns below were created using the "Pattern Editor" the best free online design tool ever to come along for us band weavers. Jeff Bigot, its creator, is always working on it to add more great tools. Thanks, Jeff! Check out Version 2 here: https://www.raktres.net/seizenn/v2/#/
