I think the subject just about says it all! I want to make some stretchy waterproof covers and the ideal material would seem to be (to me) the thin, stretchy vinyl that gloves are made of. I do want the material pretty thin and lightweight, like the stuff gloves are made of. I want vinyl/pvc rather than 'rubber' because it is much easier to glue successfully in my experience, most of the 'rubbers' are difficult and not as well glued as vinyl/PVC with a solvent weld type glue.
However I can't find any suppliers though I have had some 'interesting' results from some of my searches, not suprising really once you mix 'stretch' and 'vinyl'! :-)
Any ideas anyone?
