I use them all the time from my blinds.I have two popups. and have made several sets.one set for each window.
we have a bush that is called a sparkleberry,very hard with a lot of forks in them in them. I cut them to the right hight and drill a hole in the bottom,put a small fiberglass rod in the hole.(about 6" sticking out) that sticks in the ground to hold them in the window.you don't have to move the sticks from one window to the other.
3 in each blind would cost an arm and part of the leg.[8D].

sure makes them long shots more comfortable.wouldn't get in my blind without a set.
