I'm trying to find some of the "shade screens" you can use to put over ex-pens such as at coursing events, etc. The ones that I am interested in look like a durable woven mesh fabric and are big enough to go over the sides of the pen most of the way (I have a 42" high pen). If anyone can point me in the right direction I'd appreciate it. Thanks! 
Home Depot, you can buy it by the yard.
My husband said he got ours at Orchard Supply Hardware not Home Depot but I think it is at Home Depot too.
Cool, I'll check this weekend. I'm guessing it would be in the gardening section if they sell it to protect plants.
I am not sure but that makes sense. I think it is called "shade cloth" so you can ask someone at the store if you are having trouble finding it.
Here is a link to the Home Depot page with it on it, http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100656888
