Do NOT buy the bases from the craft stores.. they are junk. Seriously..lol. I own a soap store, i make my own soap, and trust me when i say - there are much better bases out there.. Do a search for melt and pour bases, and you should be able to find better alternatives, like all natural or nearly all natural.. Also, if you go to barnes and noble or a book store, there are TONS of books out there to try. Also, if you are really ambitious, you can try to make Cold Process soap, there is alot more involved with that method, but the results are well worth it!
Good luck!
