First I took some homemade playclay and pressed it into thin pieces on an old cookie sheet. I then just barely pushed some metal cookie cutters into the playclay. This is to seal the bottom of the cookie cutters so your wax doesn't spill everywhere! I also decided to try putting in the wicks at this point, which worked great. I just barely pressed them into the playclay.
Next, I slowly poured the melted wax from my pyrex measuring cup into the cookie cutter molds. The cup is very, very hot, so be sure to use oven mitts! (See my previous post for tips on melting beeswax).
It takes a bit for the wax to harden completely, and I was too nervous to move them into the freezer before they had set up. After they were fairly solid, though, I transferred them to the freezer and they hardened FAST! Removing them from the molds was super easy, too; just push them out and peel off the playclay! I only had difficulty removing one of the floral pieces, and that was resolved by running it under a little bit of warm water. It popped right out!
