I’ve always loved the look of skeleton keys, and realized their intricate shapes would make wonderful puzzle pieces. As I designed, I took some cues from the densely packed Greenwood Burg puzzle. A tricky puzzle, as most connectors feature key-like features very slightly modified from the actual keys in the puzzle!
Specs: 10.5″ x 10.5″. Puzzle material is 5 mm HDF with birch veneer.
