It’s been a while since I did a cored braid, and I have my home made core stand, so here we go.
So there are actually 16-tama in this edo yatsu braid, which is actually an 8-tama braid. The “core stand” holds 8 of the tama over the center while the other 8 braid around them. Now I can work the core strands one by one into the braid, every few inches, until the color of the braid completely changes. Then it changes back.
