I make mine on a frame of 5/8 inch unfinished bolding stock,
mitred, glued, and stapled at the corners. Then 3 mil acetate sheet is
stretched over the frame and stapled down. Finally, foam weather stripping
is attached around the frame's perimeter, to make a tight seal against the
window casing.

How do you fasten it to the window casing? Just screws?
