OK, OK. As a TOG wood soap mold maker, I can personally attest to the fact that M&P will jump straight out of my molds because only CP can be poured into a TOG Mold! RIGHT/NOT!
I know a lot of CPers pour just after emulsification. I pour at thin to thin/medium trace.
Use a TOG Log Mold. It will make a fine log of M&P soap. Better yet, my new TOG Slab 12 bar Mold with Acrylic Dividers! Pour and you'll have 12 precut bars of soap. 8)
Here is a picture. This pic has no liners in it, but comes with my liner system.
I use Paul's TOG mold for M&P and it worked fine. I didn't think to line it with anything but the liner it came with, and I lost about a tablespoon or so of soap. No big deal, I had it sitting on a cookie sheet.
