Where do we purchase the supplies for the Hot Air Balloon Model?
Unfortunately I can only recommend a supplier in Germany, where we buy the material for the Hot Air Balloon Models ourselves. Their web site is in English and German, so please check it out: Balloon AS. I am not sure about the conditions for international delivery though. You could also try Qualatex’ “Find-A-Pro” page. There you’ll find a list of balloon professionals and retailers in the USA, Canada, UK and other countries.
