Have you tried...

At Spark last fall, one of our classes was on felting soap.  Totally random.  It was also probably the class I did the worst at.   P.S. that is supposed to be a flower on top.  I know...

The technique basically involves taking this super-fine wool and wrapping it over and over again around a bar of soap using nothing but your hands and a basin of water.  It sounds easy but it was kind of a pain because just as I would get it in place, it would start to unravel and I would have to start over.  But my hands got really clean.  Which was probably a good thing considering I did a lot of painting and mixed media that weekend.

Anyway, I tossed it in my bin of soaps and such and kind of forgot about it until a few weeks ago.  I decided that I would never give it away and it was just sitting there...so I figured what the heck and started using it myself.

Supposedly the wool is supposed to act as a natural exfoliant or something, but to be honest I can't really tell a difference and, although it lathered extremely well at Spark while I was making the darn thing, it hardly lathers at all when I really need it to :)

So my review: skip the felted soap and pick up a loofah instead.
