After 2 or 3 years of use, my previous foam board sweep was dented and dinged, but still mostly usable, but it was just a bit too small. I had some leftover foam board sitting around, and promised Jim Grey that I’d write up a how-to post, so I made a new one over the weekend.
Really, it’s very easy to make one of these. You need 4 things: a sheet of white (or black, or whatever color) foam board, a straight edge, an X-Acto knife (or other sharp blade), and about 15 minutes.
