By the way, if you wanted to make something like this, you could use light sticks in the place of the lights that you see here. One year I made an alien in a spaceship costume for my daughter and I used a series of light sticks for the rim of the flying saucer. Her costume won first place for the entire town. You need to think outside of the box to find possible materials that would work... Anything is possible if you use your imagination.
