Problem: The mysterious gremlin in the dryer has claimed another sock, leaving its mate to forever reside at the back of the single sock bin.

Solution: Pull that lonely sock out into the light of day and play. Single socks have all sorts of uses, says Cynthia L. Copeland and Anya Lewis, authors of Lost Socks! ($10). On a rainy day, pull socks over the end of hockey sticks; the kids can enjoy indoor play without scratching the floors. Too cold for water balloons? Fill odd socks with flour and tie the ends. Then give them to the kids to throw each other (outside) for a gentler and easier-to-clean version of paint ball. Socks are perfect for sports too: Slip your water bottle in one to keep the water colder and to absorb the sweat on your hands. Use them as markers for bases or field poles. You can even play flag football using socks tucked into your waistband instead of a tag belt. And don’t forget, rolled up socks make great balls.
