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!
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 :)
