You can get camo burlap, (54"x12') at wally, along with some green plastic tomatoe steaks. Weave the steaks through the burlap and you have a very light, easy to carry blind.
While most of us wear camo, not that many of us can sit still for the amount of time needed for the predator to show itself. In my area it can be from 15-45 minutes before this happens, cats can be longer.
I use the blind mostly in spring when the ground is soft and easy to push the steaks in, you can use a piece of plastic pipe "T" as a handle to push them in with as well. Doing so allows me to move around a bit when needed and not have to remain frozen in place as the predator tries to find me, which of course makes it show itself sooner.
I'll bet you a bubble gum cigar that your score ratio improves and it costs under $20 to do. blue
