When hunting out of a blind for turkeys just throw the blind up anywhere. It can be placed anywhere even an open field. The turkeys for some reason dont pay much attention to it. The most important thing though is wear dark clothing that way you blend in with the shadows of the blind.
The best thing you can do is check out the blinds yourself. That way you can pick a blind that fits your needs and expectations. The most important part is pick a blind you have plenty of room to draw your bow. But when that day comes you can afford a Double Bull. Do it because they are definitely the leaders in blinds. Hope this helped you and good luck.
