(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!
All you do is hot glue crayons into a shape on a canvas, then melt them with a blow dryer. Tip the canvas to make it melt a certain way or to splatter a certain way, Then if you want you can glue pictures inside too :)
Crayon heart wall art - arrange in a heart and melt crayons with a blow dryer. add a picture in the middle to use it as a frame. Okay I've seen the crayon melty thing before but I love the heart/picture frame idea!
