By one, by all, and start decorating your knitwear!  They aren't just for topping hats.  They are also a great accent for tie straps on hats, as well as making great accents for scarves.  Put a pom on one end of a scarf, and a giant "buttonhole" on the other end so you can use the pom as a closure.  Come up with your own creative uses for these fun accent pieces.
