Here's a site with some really great directions on making these.
Sewing directions for Polymer Cool bands
I'd advise to use a high quality cotton for these, the more tightly woven the better, because one poster mentioned they turn into slimy balls when the crystals are wet. I have one I bought that was made from lower quality fabric, and it does ooze jelly-like stuff when I use it.
Also, some people can be sensitive to this gel/crystal stuff, so just be aware of it; if you start to break out, take it off and don't use it!
I bought the crystals as Walmart a week or so ago; i'm going to make some myself for our next trip.
