Hey that's a very smart idea to put them in the pillowcase. In fact, brillant! Of course, I kind of like the wadded up balls that I've got tossed in my linen closet right now that tend to fall out onto the floor when I open the door and I pick them up and wad them up again the throw them back in. Okay, I sort of think of it as some sort of exercise program. A lame one, but one nonetheless :)
