Kristie shares this tip in the comments below: "I just made a batch of these. The wax was a bit unevenly distributed, so I layered all 10 or so wraps in a stack, rolled them up somewhat tightly and put them in a 200 degree oven for about 3 hours. When they came out the wax had dispersed evenly throughout! It worked wonderfully!" Other commenters have mentioned using an iron to spread the wax mixture evenly. Sara describes this method: "I use an iron covered with foil. Place the cloth with wax and resin on top on a sheet of parchment paper. Cover with another piece of parchment. Iron on cotton setting with no steam until wax melts. The foil on the iron help protect it from getting wax on it. Protect your ironing board cover by covering it with an old towel or with more parchment paper."
