Review on Azobur Nylon Repair Patches Waterproof Self-Adhesive First Aid Tenacious Lightweight Portable Fabric For Down Jacket, Tent Clothes, Sleeping Bag (Golden Rectangle) by Vettee Welch

I used the transparent tape to patch a vintage nylon, U.S. flag. It blended perfectly into both the red and white stripes, was easy to work with, and is holding strong without curling on the edges. It is not super thick, which is what I wanted, because I didn't want the edges to show. True, there were no directions, but they are not needed. You cut the appropriate amount, peel off the backing, and apply. I even cut some pieces quite small for the smaller holes, and it still worked fine. I would not try to apply a strip longer than 4 or 5 inches, as it might be a little more difficult to work with. Disclaimer: I used on an indoor flag, so I cannot speak for durability if exposed to the elements.
