A really fast one is a bar-soap scrubbie-pocket made flat in garter stitch, folded and sides stitched, with one end open to slip the soap inside. Made in cotton, like 'Aunt Lydia's Sugar n Cream', for instance. With the soap inside, just wet it and start scrubbing.
Off-Topic... I looked at your blog and noticed you want a button for your new group. It so happens that I make graphics for web-sites that I build. A little corner of your space for my logo and you get a button?
If you're interested, let me know. Happy :XX:
