Hi Jenn, Sorry to take so long to get back to you, I haven't looked at this post again til today. I use the wax left over (punched out inner circles and bits around the outside of the rings) for chunk candles. I tend to use the same wax for both the rings and the overpour but to keep the overpour as clear as possible I don't add vybar or stearine. If you have different waxes then simply experiment and see what happens, I don't think that there are any hard and fast rules about it. Although you may wish to pm celicagtca as she is the creator of this fabulous technique. I'm so glad you like them. Cheers, Mozzie
