Last year for Halloween, my little one wanted to be the moon.  As in the big orbital ball in the nighttime sky.  Go ahead, Google "moon costume."  See what you come up with.  Precisely nothing that actually looks like a moon, right? So after weeks of brainstorming and days of construction, our creative two-year old was slipped into a black cat-suit, wrapped with two battery packs of led-lights and very carefully maneuvered into a giant chineese ball lantern.  She was, indeed, the moon.
