I am getting ready to make M&P soap with two of my nieces and have never made it before. They wanted to make soap with me, but I have only made CP and can't do that with them because of the lye. So, one of the girls wanted to know if we can add aloe gel? Also, can I color with natural colorants? Any tips you can give me that would be fun to add for 10 and 11 year olds? Thanks, Bnky
