Boo-tiful Button Pumpkin - Paint the pumpkin stem using black crafts paint; let dry. Print a Halloween message in a large font from your computer; cut out individual letters with scissors. Position the letters on the pumpkin, trace around them with a pencil, and remove. Fill each letter with black buttons, adhering them with glue. Tie a black wire-edged ribbon into a bow around the pumpkin stem to finish.
