Menagerie of Magic Braids
20.0 x 20.0 cm
leather, elastane
2026
Magic braids are used in leatherworking to make intricate straps and bands. Unlike regular braids, which have free ends, these braids are closed off a both the
top and the bottom. Leatherworkers craft these braids by starting with a rectangular piece of leather with 𝑛−1 slits cut to form 𝑛 strands. This object is manipulated to arrange its strands into a non-trivial braid without introducing any twists in the strips. They appear to be impossible to make. This piece displays a selection of magic braids on 3 and 5 strands.
