Can you guess what this is?
It's a Nellie's Dryer ball. They go in the dryer and make your laundry soft without using dryer sheets. They are also supposed to shorten drying time, but I haven't tested that myself. This one happened to be in the dryer with an old handkerchief, and the tatting around the outside must have been just loose enough to get caught and wind itself around and around and around the dryer ball. Doesn't it look weird?
