The typical "doghouse" type popup blind sets up easy, but I can not, for the life of me, fold it back up in its carrying sack very easily.
With it flat an turned sideways. Place your hands on the top about a foot or little more apart. Imagine yourself taking yours hands leaning over an sweeping between your legs about three inches off the ground. Grab the top side push it down with the blind up against your body. push the top side between your legs. It will start to fold. Grab one side an fold it over flat then do the opposite side the same way.
