An out-of-this-world galaxy begins with plain dark clothing and corrugated cardboard. Frank, 9, is a ringer for Saturn, while comet Mary-Kate, 7, leaves a fiery poster board-and-tissue-paper tail in her wake. The starry retinue on Corinne is strung on lightweight floral wire and fastened onto a headband with floral tape. Daniel, 6, glows in a moon mask dotted with yellow stickers. To make Saturn or a comet, simply substitute those shapes.
