I made these chunky, recycled crayons a few months ago, but the kiddos are just now coming around to them. It's a great way to use up all the crayon rejects. These are really cute. There are a bazillion places to find instructions here and here are my favs. What I really want is to make beautiful ones like these crayon rocks here (and omgosh... I want everything on this site). Will be honing these crayon rock making skills through the years, as our rejected crayon collection builds.
