You don't have to totally wrap your soap. If you search there are many options for wrapping soap. There are cigar bands, shrink wrap, shrink wrap bands and many other artistic ways to wrap your soap. I know some have used saran wrap I've not tried that. M&P soaps do need to be completely wrapped but CP and HP do not.
Are you wrapping them to sell or for personal use? How long are you curing them for?
