Dodecagon Thing

12 identical shapes make the small dodecagon; 24 shapes make the larger version. Some of the shapes have to be reflected but this doesn’t matter in garter stitch as both sides look the same.

It is an interesting shape but limited in its usefulness as any tessellation beyond the 24 shapes creates a pattern with very jagged edges. 12, or 24, shapes can be used for a cushion or afghan. 

The shapes can be made to any size, using any yarn, from very simple instructions. Some interesting optical effects can be created by the positioning of the colours.
