I want to start getting into making soaps and I have three questions, 1. When a project calls for one or more EOs, do I have to use those or can I sub with an FO that I already have on hand? what is the value to the soap process of the EO besides scent? 2. Are there any videos on the two types of lye soap-making processes? I know there are some good books out there and the step by step guides here are helpful, but for me the more visuals on the subject the better. 3. I plan to do this as a hobby and have no intention to even think of making it into a business for a few years at least, so my question is, what do I do with all that soap when I finish making it? I mean the average batch makes several bars that will each keep you clean for a few weeks at the least and while my friends love getting my freebies as some point they will have more then they could use as well. This to me is one of the biggest barriers to starting to make my own soap.
