Looking for ideas on Homemade Hay Bale Blinds. Have any of you guys made these? I am currently in the process of making my first one. I am using 2X4's for the frame and stapling cattle panels to them that are bended to create a hoop to mimic a hay bale. What do you guys recommend for the inside of the blind that will cut the wind as well as keep things dark inside. I am trying to keep this as cheap as possible and am planning on making at least 5 blinds. Also, what would you guys recommend for the outer layer of the blind. Has anybody tried erosion mats? If so do they hold up over the years? Where is the cheapest place to buy these mats? Thanks for the help.
