Thanks for the replies. Maybe I'll just visit the local fabric shop for colorful scraps
Yes, it's 80% shade cover. I was planning on guying my some as well, although it is pretty sturdy. As part of their 'playa package' page it shows one of those camping dome tents, taking a beating from the wind, and their some in pretty good shape. It's actually sorta a geodesic dome, external frame, with reinforcing itself by being under tension. Tensegrity I think is the term they used. I have candy-caned rebar to die & guy the dome down, guying, and to guy the corners. Plus a couple of straight pieces to physically tie (or put the poles over) for the corners to help keep the poles straight.
Guess I'm sorta over thinking/doubting myself some, since this is my first time.
