Ideas on homemade halloween costumes

My daughter wants to be a gumball machine. You take a clear garbage bag, cut leg holes and step into it. Fill the bag with inflated colored balloons and tie the bag loosely around your neck. You can place a box over your head or at the bottom with a coin slot painted on it and the slogan"gumballs 5 cents" It looks great if you wear a black or white sweatsuit underneath.
