So I am having some difficulty with our polyethylene covering the house. The dimensions for the structure are 14 ft 6 in. by 20 ft. 4 in., and I can only find 6 mil plastic sheeting in 20 x 100 ft rolls, which can't reach over the 20 ft 4 in side. I am hoping not to specical order what I need (25 x 100 would be great) so I am trying to think of other solutions. What do people think of overlapping poly going down the roof and back wall (which is where I need the 25 ft. section.)? Maybe I can figure out some way to seal the seam. But I do live in an area that gets on average 144 inches of rain a year, so this might not be a good idea at all. Any suggestions would be appreciated too. Also, for some photos we have a tumblr up. (Scroll down to the middle to see photos from putting up the frame of that building.) http://bit.ly/1ecI2hW via http://bit.ly/1ecI4Xk
