Iron on patches are your friend for areas like this. Curved needles as someone else suggested also work.
But because I hate my hands, I almost always just unstitch the pocket and lining, sew the patches on, and then reconstruct the pocket and lining. Probably don’t do this, I get hyper fixated on projects and do things the long way round.
Yeah, you’re pretty out of option for an older iron on patch. Curved needles are your best bet if you’re comfortable using them. I hate using them personally, another reason I’ll unstitch and hand sew it back together. I’ve got a machine to do some of the heavy lifting, though
