Can anyone recommend some good web sites or info on what makes the best ground blinds for whitetails?

I have always done my bowhunting from treestands and am not crazy about hunting from lofty heights.

My cuz that I taught to shoot instinctively shot a nice 6-pointer from a ground blind at a mere 10 yrd 2 yrs ago with his recurve and homemade cedar arrows and Magnus 125's. I'm envious.

I'd like to try more of the same but am concerned about being 'spotted' while drawaing my recurve, etc. Any suggestions for stools, set ups?

Thanks,
