Maybe it's Yo Gabba Gabba in the background and me trying to read LOL but I am slightly confused. In the first part of your post you said if your using 8 ounces worth of tart cups, then you need 8 ounces of wax. But the last part is something about subtraction (math unfriendly here) and it came up to 7.52. So do I need 8 ounces of wax like originally stated or 7.52 ounces of wax (or can I round it out. Also one other question, do I use the same amount of EO as I would FO? I plan to use EO's instead. Also, I'm learning I need more EO lol Gonna buy some Thanks again for the help, honestly, this board has taught me so much. I thought this would be ultra easy, but looks like I need more stuff. I don't have a scale or anything. I was gonna jimmy rig up a melting pot. Ghetto Tarts
