I have been hunting out of blinds for a long time. I learned that leaving your shooting windows open is best. The critters don't care and just watch your movment if you have them close and stay towards the back corners where it is most dark. Also, you never have to worry about boradheads going through mesh, especially if your shooting expandables. I have had deer stick their nose inside my blinds and never know I was there even when there was 2 of us in the blind. I hope this helps and best of luck to you.
