I use the same recipes for HP and CP! I also use a silicone mold from WSP (the log mold) and it works pretty well. I have also tried using a silicone oval mold, but they are individual molds and the soap doesn't seem to harden enough in the mold before I try to take them out (even after a few days). I have no idea how to fix that, but they always end up mangled, so I have stopped using those. I would think a tray mold would work a little better than the individual molds. If you are just looking at it for your own use and to get the hang of HP, I don't think the mold will be an issue. :-) Good luck and have fun!
