My Fitted Sheet Balls Up In Dryer

I washed my bed linens today and, as usual, my fitted sheet balled up in the dryer, with all of the other bedding inside of it.

When it balls up, it takes forever to dry, so I end up having to dry the fitted sheet separately, which I don't like because it uses more electricity and time!

I did a quick search online, and the only website that gave any real help was the Hints from Heloise (Washington Post) article that gave these instructions: tie the corners of the fitted sheet together loosely. I'll have to try that!
