Good tip on the bonded wool, PaperPrincess. I have some thrift store sport coats, and thought I could just leave the bonding on since nobody can see the backside anyway, but I wanted to try shrinking some, too, so I will be trying the steam iron approach. Kassaundra, I have a bunch of rayon Hawaiian shirts and am still collecting them; I would like to know why not to use it, and how light is "light weight"? And thanks for the "tie" tip, as I have a collection of maybe 100 also, but have not deconstructed them as yet.
