I think I'm missing the obvious here but I don't get how you use the individual molds. I have a silicone one cavity mold & made M&P and was able to melt just enough for the mold & then do it again after that one was hard. However, that would take a while if I wanted more than 2 soaps! And how could I possibly do that with CP or do you just use the log type molds for CP? Even with a 4 cavity mold, you'd have too much CP for it. Thanks
