I have had my best results by brushing it up and leaving it. Don't open windows across from each other. They will see your movement with the backlight from the other window. I also started just unzipping a small vertical section of one of the zippers. Just enough to slip the rifle and scope out. Some deer will notice the large dark opening. The best way to explain this is to set one up and walk to where you expect deer to be and look at the blind. The dark opening stands out like a sore thumb. If you are bow hunting the shoot thru mesh helps a lot. If it looks out of place to you then you need more brush and a smaller opening. I have thought about sewing in a small window myself, just haven’t found the time.
