In the Larry Niven/David Gerrold send-up of Isaac Asimov (right now
I can't remember its name), "Purple" and his native associates found
a plant-based "gum" (or similar) to use as a coating on the fabric
they were weaving for baloons. Wasn't perfect, but it worked well-enough.
(Y'know, where the main native character's two sons carved bicycles out
of wood, and were named Wilville and Orbur)

               But God demonstrates his own love for us in this: 
                         While we were still sinners, 
                              Christ died for us.
