On my last blind I used some surplus Artillary netting with a desert camo poly tarp underneath for rain & wind protection. You can go in my gallery for pics.
But thinking I might use oiled canvas on the next. I've got snaps down most of the boat anyway, so it only seems natural to use them to attach the canvas.
Hey, lets see some pics of the frame. We love looking at boat blinds!
