I have built 2 tower blind that were 6 x 6. They where 10 feet to the floor. I used green sheet metal for the walls and roof. Sold the place where they were. Bought another place closer to home. Looking at building another tower blind. Just looking for camo sheet metal this time. I found some from this place www.timelesstimbers.net. The only problem it is 22 dollars a foot. I'm not paying that. I thought about getting green and using stencils to camo the green. Does anyone know of any other camo sheet metal. I know menards has some don't like the color.
