I’m not sure you’d ever roll them for fear of smashing them into a pile of glass caltrops but it would be cool to have a pair of stained-glass d20. They’d look great on the coffee table. You know; beside the black skull, the Predator gun and ghost trap.
As it turns out you can make your own stained-glass d20 with your own laser cutting, compatible vector editor software and icosahedron jig.
What? You don’t have any of these items? Well. Ahem. Nor do I. However, Instructables has a handy guide for making stained-glass d20 if you happen to have an impressive and oddly specific collection of craft / handy tools. In fact, the helpful how-to guide even discusses what you could use if you didn’t have a laser cutter of your own – some sand blasting might work.
