Having no real interest in hunting down an out-of-print, limited edition handmade book containing computer printouts, I wanted an alternative to Rosalie Nelson’s set of patterns for Edo Yattsu (often written “Edo Yatsu”, which really sounds more like “Tokyo Punk” than a braiding sequence).
So I wrote a script to generate them. Except that even after finding and excluding the color inversions, I had 26 compared to her 24. I’m pretty sure she excluded the two 180° rotations that are not also color inversions. If you’re braiding directly onto a loop, you may want the alternative versions.
Large collection of pattern GIFs below the fold, using the standard Carey diagram. When I get a chance, I’ll change the script to generate PDFs as well as GIFs.
