Hmmm... that didn't work so well

I put the slippers in a zippered pillowcase to felt them. I didn't do that for the last 2 felted slippers. They felted properly for the most part... the bag squeezed them shut and they started felting closed... not so good. I pulled them apart and threw them back in the next wash cycle. They weren't completely felted around the ankles either... must remember not to use the pillowcase for slippers!
