Hollow out pumpkin: Turn pumpkin on its side, and use a keyhole saw or knife to carve out a circular opening in the bottom. Make the opening large enough so your hand can fit comfortably through it. Use a scraping tool to remove the flesh and seeds, scraping away the pumpkin's inner wall until it's about 1/4 inch thick. Turn the pumpkin right side up.
Punch holes with drill to create constellations; connect dots with gouge. (Or print template, then cut out and tape on formations you want to use.)
Place individual bulbs of a light strand in each hole and pin to secure, or, for a faster finish, insert one battery-powered candle.
