I made my DS some new crayons from old ones.
This is what I did...
Preheat Oven to 275F
break up pieces of crayons
sprayed muffin tin with vegetable oil
placed in over for 7 - 8 minutes (or untill all pieces are melted)
let the tin cool then put in freezer
He only had enough pieces to use 2 holes in my muffin tin but they came out great (I'm a proud crafty mamma) I'm heading to the dollar store today and going to see if I can find some silicon trays. We are going to start saving pieces of crayon again and hopefully next time I can make ones that are all one colour!!
