The Double Four-Legged Stand is made from eight hexagonal sticks and eight dowels. Each stick has four holes. It combines the geometry of the Locked Nest and Cuckoo Nest puzzles. If you know what it looks like, it's not that difficult. If you don't, it could be challenging. Number 81C-1 in Stewart's numbering system. Stewart also made Two-Three (81A) that makes a two-legged stand or a three-legged stand and Four-Legged Stand> (81B-1).
