My only suggestion is block or close windows such that light or ones vision does not have a straight through route. Otherwise, movement therein is readily visible. If one stays in the dark and back from the windows he is nearly invisible. Yes. Clear the container with the muzzle and life will be fine. Our biggest struggle is wind that might rattle the material. Wish they were made with something like soft burlap, but then rain would become an issue. Good luck out there,
