I want to make rebatched or hand-milled soap, but I'm having trouble deciding on which supplier to use. Any advice?

I've never had much luck with the rebatched stuff, but I do make Cold Processed soap from scratch. I think that Wholesale Supplies Plus has rebatch bases: http://wholesalesuppliesplus.com

Also, Brambleberry is a good supplier for all kinds of soap related supplies: http://www.brambleberry.com

If you want to learn more about soapmaking, Kathy Miller's site is an excellent resource and has a lot of links: http://millersoap.com

Good Luck!

I buy my soap base from soapwizards.com. Good service and not a lot of junky chemicals in the soap. (I would not recommend their fragrances, though.)
