When i set up a spot for my blind, i pick out a hemlock or pine tree with some branches that will lay on the roof of the blind if possible. If i trim out some small branches to get the blind tucked in better i use them to cover the roof, this will break up the outline of the top of the blind. Sometimes i have been laying a few branches on the ground in front of the blind if there are extra, i really haven't brushed it in real heavy yet, there is a lot of foliage still on. Later in the season i will find out what works and what wont. This is my first year at this and I'm kinda flying by the seat of my pants. After this season i will have a better idea of what to do. But so far i have had 7 deer inside 20 yards and only one of them acted nervous about the blind but still came in for a closer look. The rest of them paid no attention to it at all.
