On a bright, sunny day, use the natural warming power of the sun to fluff up your flattened down pillows. Find a sunny place outdoors, and place a large towel or clean tarp on the ground. Lay your pillows -- bed pillows, decorative throw and even comforters -- on top. Let the hot sun do its magic: It’ll warm the down feathers and help evaporate the trapped moisture inside. As the pillows dry out, they’ll magically fluff up. The sun will naturally deodorize your items, too.
