My wife heard about a trick to speed up the drying time of your laundry, and it involves Tennis Balls

Basically, you take a few tennis balls, and put them into an old sock.  After each ball is put into the sock, tie a knot.  Then, repeat the process until you are out of tennis balls.

Next time you do a load of laundry, place the "tennis ball socks" in the dryer. it will speed up the drying time! It's really great for drying comforters, fluffy coats, pillows, or anything else that could use a good fluffing.

Here's what it looks like.
