(image) What a great idea for the kids / grandkids! Perfect DIY project & recycle those used / broken crayon pieces, too. Would make for a great party favor, gift for Valentine's Day (or other occasions) or gift from Teacher to Students! Love it!
How to remove crayon from a silicon mold. Generously spray no stick cooking spray into the crayon affected areas in and on mold. Let sit for a few moments and crayon residue will easily wipe out. Wash mold and your good to reuse the mold! No more leftover wax!
