Elf table leg covers - Sold Out but a friend pointed out they'd be so easy to make. Use Christmas socks or girl's tights and cut out felt elf shaped shoes, glue together and stuff with batting or plastic grocery bags. Cute on a kid's table!
Family Fun has an fun idea for your snowman party -- Snowman chair covers. They have a tutorial with a little sewing involved, but I think it would be a little easier to use a white pillow case and then glue some felt pieces and buttons or pom poms on.
