Crayons in glue stick containers. By far one of the coolest ideas for old crayons pieces and glue stick containers. Melt down crayon pieces and pour into glue stick containers to harden. Big crayons that can be rolled up as they are used.
Use duct tape for words. Place crayons on top. Blow dry on high heat till crayons melt. Blow dry side to side to blend colors. Slowly remove duct tape to reveal words. I've seen the crayon thing before, but love the duct tape idea!
