As far as Knitting Stretchy Fabric if you want to use the material
As far as Knitting Stretchy Fabric if you want to use the material for a trampoline, we can't speak to that, but we do know that if the material is over 150 grams per square inch, you should be able to make a hammock out of the material that would bear most people's weight. Not that this is a preferred usage, mind you, and in fact, we would advise against such a usage unless the parade is a one of a kind event and you won't be using the fabric again.
