I put them in the oven on 350 degrees and sat there and watched them melt. I wasn't sure how long it would take, so I wanted to be careful and make sure I didn't end up with a boiling waxy mess. I didn't stir them or anything, I just let the heat do it's job, and it took about 5-7 minutes for them to turn into liquid.
I took them out to let them set- about 15-20 minutes- and then popped them out! They came out really easily and hardly left any residue in the tray.
I think they turned out really well for my first batch! I discovered that it's best not to mix dark colors together, like blue and green- unless one of them is very light. Spencer really likes them and they are a lot easier for her to hold than regular crayons.
Up close and personal with the heart crayons! All in all, this was probably the easiest craft I have ever done and it's also the one that turned out the best- at least in my opinion. And you could do it with any mold, for any holiday or birthday- I can't wait to make four leaf clovers for St. Patrick's Day!
