This recipe makes three 6-oz jars, two 8-oz jars, or one 16-oz mason jar. This is just an estimate, so if you find that you didn’t end up with enough wax, you can easily melt some more and top off your candle/s. To get an idea of how much wax flakes you’ll need, think of it as needing double the size of your jar. Keep in mind, that every fragrance oil and essential oil are different in potency. Only you can get a good idea of how much to use in your candles depending on how strong they smell. I find that essential oils have a stronger scent to them then fragrance oils do. Therefore, add more fragrance oil than you would essential oil.
