Also drill on the other side so that the wick stays straight in the candle.
Once the wax is completely melted, add your dye. Mix with a disposable wand or spatula. Take a few drops of the wax plus dye mixture and place on a sheet of scrap paper. Wait until it cools to get a sample of the color. If you find the color too light, add more dye. If the color is too bright, add wax to the water bath. Be aware that the color will be a little brighter than your sample.
When you are happy with the color, add a few drops of perfume and then gently pour the wax into the mold.
