I put together a canopy that was made of ripstop nylon and PVC. Took two pieces of 10' PVC and cut in half. Added screw connectors on each end, this allows to separate and stow easily. attached eye-hooks to the caps put on the outer ends and used bungees to secure to lifeline stanchions. All together it cost less than $15. For shade I had a lite weight rip stop 9.5' wide and 10' long and the same made of sunbrella for rainy days. I don't remember the cost of material, I bought it online because it was cheaper than buying locally.
A people that values its privileges above it's principles will soon lose both.
