Yes melt & pour. My cousin told me she lets her M&P soaps sit for at least 3 weeks to "cure." But from what I've read on this forum, they don't need to cure. Maybe she was getting mixed up with CP soap?
If you let your M&P soaps sit too long, there's a risk of them shrinking, not to mention all the dust etc. that will stick to them.
It's always best to wear gloves when wrapping them so as to not leave fingerprints on the soaps (not very attractive to get a soap with a big thumbprint on it...)
If you use cling wrap (Saran Wrap and the like) you can always use a heat gun (carefully) to get rid of folds and wrinkles but the scent will eventually seep through the plastic. Cellophane will keep the scent in.
Depending if you're giving/using the soaps soon or if you're making them way ahead of time, you can chose the material that suits your needs best.
If you chose cellophane, you can always keep one sample in cling wrap so customers can get the scent.
