Drafts from poorly sealed doors and windows are to blame for chilly homes and skyrocketing heating bills as the temperature drops. While repairs and sealants are the best way to block drafts, one DIY solution can help you keep your home warm on the cheap. All you need are two neckties (about the same length and size) and a needle and thread. Placing one tie on top of the other and sew them together, leaving a small hole at the top. Fill the tube with pebbles or dried beans before sewing it shut. Place the snakelike tube along the edge of a chilly spot to block the draft for good.
