Oh boy, where to start. The possibilties for recipes are endless. You must decide which fats you want to use, and which liquids. I use olive oil, coconut oil, goats milk, and water. After you choose your fats/liquids you want to use, you go look up a soap calculator. Lots of them online. You plug in the ingredients you want to use, then the calculator tells you the amounts for the size batch you want to make. I use the cold process method, and make 3 different scents. Same recipe, just vary the essential oil for fragrance (optional). I found a recipe that works for me and is consistent, so i've stuck with it. But like i said, the ingredients you can use are limitless. Highly recommend looking up some basic recipes on YT then branch out from there. Its simple, but you do have to measure very carefully.
