Have you ever heard of mixing soap from the cold process method with the soap from the melt and pour method? Marla Bosworth from Back Porch Soap Company came back from the 2011 Soap Maker's Guild Conference in Miami, Florida where she presented two classes on two topics, "How to Successfully Wholesale" and "Wild Child Soapmaking: MP and CP Combos."
In her article "Wild Child Soapmaking Techniques: Mixing Cold Process Soap with Melt and Pour", Marla has beautiful pictures on Cold Process Soap with a MP swirl and Cold Process Soap with MP Embedds. She has kindly shared a Cold Process and Melt and Pour Whipped Soap recipe for everyone to try. So if you want to go on the wild side and try this technique, then I would say go for it.
