Has anyone had experience with creating custom-shaped inflatables? Like airbeds that you blow up with a pump, but in different shapes?
I’m considering this for a costume that needs a lot of volume, but which I’d like to keep light and also to be able to deflate and pack down small. A flat airbed shape isn’t going to work, I need something more spherical, but I guess the rubber sheeting and pump dock from an airbed could be re-used, if I could change the shape of the rubber.
I guess the key thing would be airtightness, although it wouldn’t matter if it leaked slowly, as it would only need to stay inflated for a few hours.
Anyone got a double airbed they don’t want?
