I have a roll of material that was used by Westinghouse Corporation in the manufacture of linen Micarta. It's light grey on one side and a darker gray on the other. I just cut it to size and wrap all of my ladder stands and tower blinds with it. On the tower blinds, I staple the material to the wooden frame. On the ladder stands I use the plastic electrical ties on the top and bottom of the frames and on the vertical supports, just leaving the access points unattached. Since I have them in trees with the limbs and other natural foliage around the blinds, the wind blowing the material isn't distinguishable and over the years has never alerted the deer. This material does eventually rot and tear from the weather, but each year I check it and if needed, just replace it. I've seen similar material for sale at a few outdoors dealers, and it's available in a camo pattern or a solid green color with the prices based on whether or not it's camo. This stuff is semi-rubberized and will actually stretch so that it can be wrapped pretty tightly, which also eliminates flapping in the wind and repels water.
