I know that Richard Bach counted on his ability to distinguish ceconite from cotton to establish his credentials as a serious aircraft buyer. Fabrics can be layered.

Ceconite is also known as Dacron and is used in aircraft skin. I use the tarp material that covers wood products during shipping for my chicken wire laminate.

Aerodynamics of the flying snake Chrysopelea paradisi: how a bluff body cross-sectional shape contributes to gliding performance
https://jeb.biologists.org/content/217/3/382


Quote:
A prominent feature of gliding flight in snakes of the genus Chrysopelea is the unique cross-sectional shape of the body, which acts as the lifting surface in the absence of wings. When gliding, the flying snake Chrysopelea paradisi morphs its circular cross-section into a triangular shape by splaying its ribs and flattening its body in the dorsoventral axis, forming a geometry with fore–aft symmetry and a thick profile. Here, we aimed to understand the aerodynamic properties of the snake's cross-sectional shape to determine its contribution to gliding at low Reynolds numbers.
