My backyard canopy is holding up great! The kids love sitting under it when there is a breeze, it fills up like a parachute. At night my deck light lights it up. 

Here is how I made the canopy:

Using coated 1.9oz Nylon ripstop,  My deck is 19 x 19 feet so I bought wholesale and owfinc cut the lengths for me.  They were VERY helpful. I sewed the 60" strips together making a big square using polyester thread, sealed the seams put aside to dry.  Installed six hooks. Three in brick wall and one atop each wooden post that I cemented in the center and two ends of deck.  I then took the square out and marked where I would put the 6 Grommets (1 in each corner and center of poll and opposite side). I did not put support on all sides due to rain runoff, (I have no gutters) this keeps it from  puddling on canopy.   I reinforced the ripstop with  6 inch x 6 inch canvas squares on both sides of material where I was placing the grommets for strength.   Once I got the grommets in I put them over the hooks to check the fit. Now only thing left is to hem the canopy.  For the center support I use an extension pole placed in table instead of the umbrella.
