Had to register so that I could THANK YOOOOU for this tutorial!! I've been drooling over the Magic Massage cloth for awhile, but was penny-pinching... and now I just made one for $4! I have enough fabric for another.. one for work, one for home!
The costume satin that I purchased was labeled as handwash/line-dry, but I was able to quick-cycle it in the washer and ultra-low dry it without a problem (and it dried FAST!). Yay!!
