envelope
has any body tried treating porous envelope fabric with any substance, ie tent proofer??
Hello,
Is there any computer software available for graphically designing envelopes? I.e. I would like to assign colors to individual panels and view the envelope in '3D'.
Thanks,

It was the envelope that I meant. That's the same material as parachutes isn't it?

Kevin Uliassi's envelope had the capacity to hold 280,000 cubic feet of helium, and 120,000 cubic feet of hot air.
