I have a large window in bedroom that is actually 4 panes by 3 panes. Last year I covered the whole thing with plastic. The panes are recessed enough that I am planning on making a storm window for each pane. I am using 1" x 2" to make each frame and then will staple plastic to each frame. Question: Where do I get clear plastic? From what I am finding, what they call clear is actually cloudy. Is there such a thing as clear plastic that is actually clear?
