I am such a good girl...I am not hijacking the thread on Permatex seam sealer to respond to a question about fabrics...I thought I'd share what info I have on outdoor fabrics here...

Outdoor Wilderness Fabric, Inc is a good place to start...they also sell zippers, cool hardware and looky, clear vinyl for windows in fabrics...

Seattle Fabrics sells stuff that more oriented to the boating crowd but they have mosquito no-see-um mesh in various colors, which is cool....

And Specialty Outdoors kindly lists many other resources...

I hope these help some of you looking for fabric resources...
