Michael, we had some shade cloth given to us that had been used in a nursery. I don\'t know what particular type it is. My husband just threw it up on top of the runs and spread it out the best he could. It gets caught on the wire so it has some folds in it which actually works out better because it provides heavier shade. I would suggest attaching it around the edges somehow because the wind catches it and blows it down over the edges in the way of my run doors(one more project for Dick!).
