My first batch was 8 pounds, it worked for me. I soaped "Rachel's Tried and True" from Miller's site, used a dishpan with a garbage bag for a liner. Use any box that you have and line it with freezer paper, garbage bag or a shopping bag turned inside out so the print won't bleed into your soap. You don't have to have a fancy mold to make great soap! I also think that experience is the best teacher, figure out ahead of time the method you want to use with your goat milk by careful research, then if you like it, fine, if not then back to the drawing board to find another way to incorporate your goat milk. I have milk frozen, canned and powdered on hand to soap whatever way suits my fancy at the time. It is really good to try different ways to find what works for you, just remember to always use safety precautions when you are soaping.
