I agree to all of the above.

The way it was told to me when I got my 1st blind, at the time primarly for turkey hunting, "put your blind in a blind" meaning to put your pop up in a natural blind and simply use your pop up for extra concealment. But, if it's not possible, just use the surrounding foilage for brush in, and just like a duck blind, Brush it once then brush it again.
and don't let anyone tell you that they don't work b/c they are great in the right setup
