I have been wanting to make these star crayons, to recycle some broken crayons, for a long time now. I finally did for 2 of my nieces for Christmas.
They were really easy! I have a silicone star shaped muffin pan I bought just for this purpose that we put broken crayons in, then put them in the oven at 250 degrees for 5-10 min. Both of my boys helped fill the stars. My 5 year old was especially fascinated by the end result. Once they were cool and we popped them out, we had to make another set for ourselves. :)
Put a bow on top, and they are all ready to give as a gift.
