my idea was to put them on luggage, of course you can put them on anything you want. However, they do not have the “iron on” backing. I have learned they stay much better using fabric adhesive. My favorite kind so far is FABRI-TAC. Spread a nice layer on the back of your patch, place the patch where you see fit, put something heavy on it and leave it for a little while. You can get it at your nearest craft store. It’s clear and goopy. The thin, white fabric adhesive does not work as well and the spray on stuff doesn't work at all. Of course, if it's sew-able, SEW IT. That's the best.
