I'm a newbie but for CP you let it cure 4-6 weeks (unless it's something like Castille, that does need a long time to cure). If you're in a hurry, then you might be more interested in Hot Process - I haven't done that yet but I believe it's ready to use almost right away. CPOP is ready sooner than straight CP. I'm not in any hurry so I like the simple straight-forwardness of CP. When you make candles to sell, you test and retest your formula before you try to sell it. Letting soap sit for a long time to see how well that formula soap lasts, is just part of testing. Experimenting with oils, colors and fragrances is part of the fun.
