Hidden hunter blinds, have Velcro on the screens. I didn't get a camo pattern on the screens. You don't have to worry about the Velcro, because you're not moving or replacing them in the woods. Most guys take them out when turkey hunting. I have had enough double bull blinds, that I purchased extra screens for and I am making camo screens for my Hidden hunter blind. you can take your screens out, IF you brush them in really well. Wear black, wear a black glove on your bow hand. And place a small branch on the inside in the center of the window with other branches on the outside along the edges of the window. So that when a deer comes up or is coming up, you can take the one in the center away. Carefully of course. But, I've had mine really well brushed in, and my glasses still gave me away. In my wife's words " she is looking straight at your face" the deer did circle back behind us, and then came around the front again. But as they say she was on Redalert !!!
Any kind of ground hunting is just a lot of fun !
