Are these any good? I'm under the impression that I could follow the instructions and succeed, but are they too challenging for the non-talented?

Is one kit better than another? Is any kit sturdy enough?

I would be using good fabric, which I don't want to waste on a shade that falls apart. And I would operate the shade daily at least twice.
I would use the entire 41" of width, but only about 3.5 feet of length.
