I forget the name of the woman who did the Laser cutter class at the Menlo
Park tech shop.  She did a dorkbot once where she brought samples of all the
things she etched and cut with the laser.  One of the things she handed out
was tiny cotton denim patches.  They didn't fray any more than cut fabric
did.  In fact, I'd argue just a little less.  The etching on the surface of
the denim was pretty neat, too.
