TJ, McNett has some adhesive tape products that I have found to be useful for making easy repairs on various fabrics including neoprene. I found that they work better on finer fabrics like ripstop and taffeta, not so sure about heavier cordura. With these tapes, I've gotten successful long term repairs on wetsuits, goretex rain gear, ski pants, gloves and tent fabrics.

Our local dry cleaner (Pine Bush) has also done machine alterations and repairs. Most commercial and even home sewing machines can be adjusted to handle heavier fabrics, maybe just inquire at your local cleaners.

And for the heavier stuff, I visited a local sail loft for some successful heavy stitching.

Good luck.
