What you will need:
*A silicon mold tray that is heat friendly. We used this Skull and Crossbones tray, it was only $4.65 (free shipping with amazon prime)
*2-4 dozen of Assorted Crayons - I mean, what kid does not have a huge shoebox full of broken and random crayons. That means this item was FREEEEEEEE since we already had it in our house. SCORE!
