Try This: Draft Stopper

Stop cold air with this homemade draft blocker.

Step 1: For the front, cut a piece of black felt about 31/2 inches wide and the width of your door plus 2 inches. (For example, our 36-inch door needed fabric 38 inches long.) Cut an assortment of circles, rectangles, squares, and lozenge shapes out of contrasting colored felt. Make sure they fit on the black strip so there’s at least 1/2 inch between the top and bottom and the black felt edge. Sew the shapes either by machine or by hand onto the background felt. In a pinch, you can attach them with nontoxic fabric glue.
