One of the first TFA palindrome skeins I managed to snag off Ravelry destash was a skein of ‘Prism’. It turned out that the colour runs on Prism were too short to line up easily, so after a few frustrating attempts I just warped as usual and let the colours do their thing. The result is interesting, the darker purple bands seem to ‘change frequency’ partway through the scarf. I don’t think they’re my colours exactly, but it’s bright and fun and I like it a lot more than I expected to!
