These are sized for a child's wrist. The front one is from this pattern, using pink floss instead of black, the middle band is the Chinese Ladder style, which is forward knots wrapped around all the other strings in the band, for a set number of stitches before swapping strings. The back 'band' is just some leftover floss that looked too pretty to throw out. I'm hoping to be able to fasten it somehow, perhaps with a safety pin. These took roughly an hour or two each.
