Melted crayons art. This was easy and fun. I bought 3 small canvas' from Walmart for $4.00 and 4 boxes of crayons for $2. Glued on the crayons, put some scotch tape down for the "letters" I wanted and used the blow dryer to melt the crayons!
Crayon shavings or chunks in glass ornaments, heated up to melt and swirl. I definitely would prefer this over the acrylic paint that you have to drain after swirling, messing up the paint's effect so that it blends too much. This is a definite have-to this year!
