This thing was a bear to sew. I mean, making the pocket was easy, I just used an old cloth napkin and cut out the old one as a pattern. It was sewing it in that was the problem. It was just difficult to get the sewing machine into the pocket to sew it, and I almost sewed the pocket closed about twice.
Anyway, I'm pretty proud with how it turned out, and I think it was way smarter to replace the pocket instead of trying to patch it.
