Once you have your ground blind set up and tied down where you want it, you can then start to brush it in. The main goal of brushing in a blind to is get rid of the sharp edges and corners of the blind to give it a more natural look. I like to use natural vegetation from around the area I am hunting.
Tall grasses, cornstalks, pine, and cedar work great if they occur in the landscape you are hunting. When collecting materials you will need a folding saw for the larger branches, pruners, and some zip ties for holding everything in place. When covering the blind don’t worry if you cover the windows as you can use the pruners to cut any obstructions out of the way once you get into your blind.
