I just bought some iron on vinyl. It is a brand called Therm O Web and I "laminates and protects fabrics and many other materials. (water resistant, durable, UV rated). Basically you fuse it to your fabric and then use the fabric to make whatever. It is clear and lets the fabric "shine" through. It was recommended to me and I haven't tried it yet. You can buy it at Hancocks (not sure where else). I found it stocked where the interfacing bolts were located.
Looks interesting. I'm going to try it on a couple things to see how it really works.
