Shout out to Brian Whitley for naming this pattern; his was one that jumped out at me as I read, and stuck with me later on when I wasn’t at the computer. I had a hard time selecting a name from the many excellent suggestions made by the members of the Facebook Pin Loom Weaving Support Group. (I’d run out of ideas for names and had resorted to calling my new designs Uuuuh 1, Uuuuh 2, etc. “A Run on Diamonds” was formerly known as Uuuuh 4b.)
