Good afternoon Doug,
I don't think anything will adhere to the nylon mesh that won't possibly weaken it. Stitching would be best.
I would just take the whole sheebang to a sailmaker and let him figure it out - they're good that way. It might be simpler than you think.
One other thought, get yourself a sewing palm, an upholstry needle, nylon thread, and do it yourself. a little " IXXXI " pattern should do the trick. Do not drink while doing this however, a needle in the finger could hurt ... not that I would know.
