Who does it? I'm rocking the EU palmolive (w/ tallow) stick and cella. It's incredible and the scents fuse beautifully. I smashed up the stick and folded it in to the soap like they do at ice cream parlors and molded it in to a pyrex bowl. What do YOU use?
Hey Mang, you do whatever blows your hair back. I have not mixed any soaps as of yet... but I will never say never.
I use frankensoap when I travel. Better than tossing perfectly good soap away when you only have a sliver left.
I grated half a puck of both Williams and VDH. Then mixed them together well and pressed into a mug. The end result is pure synergy. The mixture performs better than either of them alone. Now I plan to put the same mix into a deodorant tube to try it out as a shave stick.
One of my 4 mugs is usually a frankensoap blend of shredded Arko and something else (slivers, remnants, etc). So far every blend has been a success.
