Hello, I have a number of pants/shorts with a bunch of rips. They'll need patches/reinforcement. Hopefully something nicer/faster than my poor hand-sewing can accomplish. I have spare material for several of them, but if you can provide a bit of tear-resistant material as a backer for some others I would be grateful. I work at the Repair Cafe, so I'm usually too busy to get them done there, and there's possibly too many that I wouldn't want to take up all their machine time.
