I built one a year or so ago, just to see how easy it was. Got the idea out of Wildfowl, I think. May have been off DHC, can't remember. Pretty easy and effective. I've killed geese out of it and it works pretty good. Used two pieces of emt conduit, threaded rod, 4 90 degree conduit for the legs (two of which are shortened), 4 couplers, two pieces of fast grass panels, some velcro, some bamboo pieces to keep the fast grass from sagging, some stiff wire to form the opening for my head, some raffia to camo around the sides/ head, a piece of plywood for the backrest that has been carpeted and some rolled up carpeting for the headrest. Got 4 rubber feet to fit on the ends of the legs, did some spray painting of the grass and put a little camo net for pulling over my face.
Here's a pic of the finished product and a link to all the photobucket pics of the build:http://s766.photobucket.com/albums/xx30 ... t%20Blind/
