Bill, we got some scrap --large pieces--sunbrella to match the color of our cushions. We cut to fit each window & sewed--Lois did the sewing, might want to talk to her about that--I removed the corner screws from each window & replaced them with screw in snaps--male end-- got the snaps when we bought the scraps. Had the canvas shop where we got the sunbrella to fasten the female part of the snap to the curtains in the appropriatte places. They work great--give us the privacy we want & store very easily under the table. After using them a couple of times we figured out that numbering them would help the installing process. We got this idea from a CD22 that Les was outfitting that I believe ended in New Jersey.
