Has anyone found a small loaf mold? I have a 42oz silicone mold and it's awesome. I love being able to put inserts in to do swirls, etc. The only problem is that it's a LOT of soap. Sometimes I just want to make a small batch to test things out (or so that I won't get tired of one type of soap) I found a few individual silicone molds on Amazon that I might try. But I'd really like to find a loaf style so I can do patterns. Alternatively has anyone blocked off part of a rectangular mold? I'm thinking I might be able to put some cardboard in the middle of my 42oz mold, but I don't think it would hold the pressure of the soap batter on the other side. Any ideas are much appreciated!
