Where might one buy pom poms for a girl's Halloween costume?

Pom poms may be purchased both online and in retail stores. Around Halloween, bigger stores like Walmart and Target usually have them. Otherwise, costume stores and specialty sports stores will likely carry them. Alternately, pom poms could be made from materials purchased from a craft store like Michael's. Online pom poms may be found at Toys R Us and on eBay.
