Milk Jug Ghosts

I got thie idea to make these milk jug ghosts at Family Fun.  I know they look a bit "junky", but I liked that it gave our milk jugs another use before recycling them, they were free to make, and I don't have to store them year-to-year.  S must really like them because the other day we finished off another gallon of milk and he said "boo" to tell me to make another one (or he thinks a milk jug is called a "boo").
