I'm looking to build a large shade structure for our camp. Essentially I'm trying to make a shaded area that will go over our yurts and tents. Our camp consists of about 60 people and there will be anywhere from 10-15 yurts based off of the standard yurt design that's been floating around. This is a rough layout of how the camp will be:

The shade structure I'm trying to build resembles this design:

I've found a few articles online about how to build this. However they weren't 100% clear on some things.
1. Does anyone have solid plans/instructions for this design. (no idea what length/width tubing, what to use to tether to ground etc)
2. What size should each section of shade cloth be? I can order it as small as 5x5ft and 100x100ft It seems 20x20ft strips are the most cost effective.
3. What is a good place to source this stuff? Our camp is based in NYC but we have some camp members in reno preparing.
4. Any other general tips or helpful info would be great.
