Paint the entire outside of the bag white. Kraft is dark so two coats are necessary: let the first dry for fifteen minutes before the second. The bag should look bright white with no brown showing.

Once dry, paint the ghost's face on the bag front. Position the eyes in the upper third of the bag (above the fold, on the base flap). Use the size 6 brush to paint two large white oval eye whites, then the size 2 brush to add black pupils once the white is dry.

Paint the mouth below the fold line using the size 2 brush and black paint. Placing the mouth here means it appears to open when the puppet is operated. A wide O shape looks startled; a horizontal curve looks cheerful.

Add thin wiggly lines below the bag opening with the black marker to suggest the flowing hem of the ghost's body. Keep the lines loose and uneven for a more ghostly effect.

Let everything dry for at least twenty minutes. Operate the puppet by flattening the bag and inserting your hand: four fingers in the upper flap, thumb in the lower, exactly as for any paper bag puppet.
