I have question for y’all. I got a great new pack and I’d really like to put an Esee patch on it. It’s one of the older khaki colored ones. At one time it had a Velcro back but that has been removed. The area I would want to place the patch is double lined so I can’t directly sewn on the patch or can I ? Anyone ever fabric glue on one. I don’t want it to soak though on the patch or the inside of the pack. Any ideas?
