If your thinking portable, I can help you. Take 4 metal stakes, some of that green snow fencing and some zip ties. zip tie the fencing to the poles on both ends of a 7-8 foot peice of fencing, or how ever long you want. then zip tie the other 2 poles about 2 feet into the middle of piece of fencing. Get the fenceing that's either 4 or 5 foot high. Then weave grass and other natural veggies into the fencing and you got your self a good blind. I've built a few and they work like a charm. When you set up the blind make kinda a half rectangle out of the 4 stakes.
Sorry for the bad instructions. It's late and i'm typing fast cuse i need to get to bed. If you have any questions shoot me a PM...
