Try This: Draft Stopper

Stop cold air with this homemade draft blocker.

Made of easy-to-sew 100 percent wool felt, this draft blocker takes just minutes to make. It sports modern, graphic felt shapes in four contrasting colors on a black background. Here we used a pleasing—and simple—visual rhythm of a shape within a larger shape, but you can be creative and invent your own. The handles allow the draft stopper to hang conveniently on your doorknob.
