The only reason I have been doing the melt and pour method right now is because the weather outside is too cold to attempt (safely) using lye. Don't have a good place here to use it without a ventilation and health concern.
I was running low on soap and needed some soon and the melt/pour doesn't need weeks to cure. So for a temporary fix, I tried it and it really lathers up quite well. It's a nice fill-in alternative.
I do like the idea of no curing time...
