you can also used recycled felt. For applique, I would go with women's blazers or suits, which yields a nice weight product. Look for 100% wool, dry clean only labels. Deconstruct the garment. If any of the sections have iron on interfacing, remove it You might have to experiment a bit with this. Use a press cloth and work on the interfacing side. start with a dry iron and if that doesn't work, go with steam. The heat will reactivate the glue and you should be able to pull it off in sections. Put the pieces in a lingerie bag, wash on highest heat and agitation. I usually dry flat. Lots of felt for not much money.
