I think it is a good idea. With undulating hills, and ravines, and what not, it is can be very difficult to determine if another hunter is in your line of fire.
The hunter across the way from me has a blind and he has an orange jacket nailed to his blind.
It flaps all kind of crazy in the wind. He has no porblem getting deer. I would think a nive blaze orange camo pattern all over a blind would not affect the taking of a deer.
