Have you ever put a pillow in the dryer and had it come out a misshapen mass that you couldn’t rest your head on without needing serious chiropractic care? I had it happen a few times and began to worry there wasn’t a way to ever have a washed pillow come out in its original shape. I thought (especially with a young child), it might be better just to buy the cheapest IKEA pillow you could and say goodbye when it got dirty or squashy. Not the most Frugular approach. But then I read somewhere that a few tennis balls might do the trick, and boy do they. I use three for a single pillow and it comes out nice and fluffy. Invest in a can, if you don’t already have some on hand, and you’ll stretch your pillow dollars a lot further.
