In the background you can see the tulle covering my raised bed of greens. I got tired of losing everything to cabbage moths, and this has worked like a charm. The hoops are 4' rebar with 10' PVC pipes simply bent over and slipped over the rebar. I had to cut nothing but the tulle--this frame was set up easily in about 10 minutes. The tension from the arced PVC holds the height of the hoops as high or low as you want them. They don't have to be secured at all. (In the foreground you can see the rebar/PVC setup more clearly, but the cover is bird netting.) Then I just draped the tulle, cut an extra piece to cover the top and pinned it in place with straight pins, anchored the bottom with rocks and made sure there were no gaps anywhere for the flying buggers to slip through, and it was all good. I've been enjoying the best greens ever! Until now I'd never heard of anyone else using tulle, so I love this article! I'm a costumer by trade, and it just seemed like the obvious solution to me.
