And here's another really talented guy's 12ft/3.7 meters long envelope....
He used my Silver 37 3/4" film made by Glenroy, Inc. (WI, USA) and used the shiny side inside and the heatsealable side on the outside, to give a matte appearance.
The picture (left) is my film which was used to make one of the 3,000 custom (arrow) balloons created for the You Are Here art exhibition in 2015. (
All the film I sell is heat-sealable and easily!
I'm amazed at the creativity and mastery that's out there ! :)

Minimum order: 10 yards
All my film is heat-sealable and all the photos are pictures of my film or made using my film.
Check out the thorough review of my film on a niche airship modellers forum! There's lots of information including how to make a valve. Start post/comment #27 through #34
