First you'll need some candles. You can use old candles that are down to their last bit, ugly broken ones you don't want/use anymore, or find some on clearance. You are going to melt them down after all. I got mine for 40 cents a piece on clearance at walmart. You will also need some free standing wicks. Which you can find at any craft supply store.
You will also need some type of container to put your candle in. I prefer glass so you can see the colors. Especially if you're going to melt and layer multiple colors. I used teacups that I got for around 25 cents each from the DI. You can easily find these at thrift stores, good wills, yard sales, etc.
Now for melting the wax. You can use a double boiler if you have one. But I don't have one because I am a terrible cook. If you are like me, you just need two pots; a large, and a small one. In the larger pot, bring water to a boil and hold the smaller pot over the top. Be careful not to put the pot IN the water, just above it. It will melt quickly and the steam is hot so be careful! Place your candle remnants in the pan and watch it melt!Carefully pour wax into your container and leave to dry for 24 hours. Its ok if you get a little wax on the outside or the rim, you can clean it up later with a hot wet rag/paper towel.
Cut the wicks, clean the container, and you're done! They are beautiful home decor, great party favors or neighbor gifts, and inexpensive to boot!
I adore them:) Feel free to ask me any questions and if you make some, post a link!!
