Hi all. Ive been looking back over as many old posts as I can find but dont see what Im looking for. I am about to make my run. It has to have a wire or net on the top because of hawks. So how is it I attach this wire roof across the yard? Do I have to run lumber across like a porch cover? Gee Im gonna go broke! The yard is kinda an L shape about 15 x 20 at the largest part. I was also considering using shade cloth as the roof but still...how do I make that stretch? Any photos?
