"Can anyone suggest a source for waterproof paper? We want to Fold cranes for the (high humidity) Conservatory & Botanical Gardens In 36" and 48" size (Orange/Red/Violet). I've been trying to find „Yupo“ paper without success."
————- Hey Sue, have you tried Tyvek? It’s actually made of plastic fibers. I’ve used it with success for small cranes, but it’s available in different sizes and grammages. - https://en.wikipedia.org/wiki/Tyvek Cheers, Matthias
