Joe's birthday was this week and one of the things I made him was a soap in a sweater. I found the very easy-to-follow directions here. So now the soap has its own built-in wash cloth. :-)
Step 1: Card Misc. Scrap Wool to make a mini batt
Step 4: Wrap batt-wrapped-soap with a loosely knit mesh netting with attached single crochet rope for hanging
