Hello! I just took up the hobby of soap making recently with a kit, and have already ordered some supplies. Before I start making some beautiful melt and pour soap though, I have a couple of questions for you guys. First of all, I was watching some MP soap videos, and I noticed that almost everyone uses the normal glycerine base, but they also use a goat milk soap base. Is the goat milk base necessary? Or could I get away with just using a glycerine base and still produce beautiful soaps? Also, I did order some 99% isopropyl rubbing alcohol, but is that the only kind you can use? Or will a 91% percent or lower work fine as well? And finally, if I were to sell some soaps at a farmers market in the future, what prices would you guys deem fair but still able to get me a profit? Thank you all so much ahead of time!
