What a great idea! I had never even imagined that you could make an iron-on transfer using crayons and sandpaper. I'm always looking for fun ideas, and when I happened upon this one, it was put at the top of my list of craft projects to try at home. I'm sure my kids would love it since they both love drawing and coloring and I love the idea of being able to preserve some of their very own artwork on a shirt they can wear!

And if you have tried this before, please share your results here! I think using a coarse sandpaper will "capture" more crayon and therefore transfer better, but who knows. Also, since my disaster of trying to melt crayon bits to make fun new multicolored crayons I have learned to use top quality ones!!!
