Try This: Draft Stopper

Stop cold air with this homemade draft blocker.

Step 3: You can fill your draft stopper with a number of materials. Sand works, although it’s a bit heavy. We used about 2 to 3 cups of rice for ours. You can also try dried lentils or course cornmeal. Don’t overfill; the stuffing is meant to plump up the stopper and make it just heavy enough to stay put. Machine sew the end closed.
