In order to make a Tri-Shutter Halloween Card, you will need the following: card stock, fishing line, ribbon, paper trimmer, printed/decorated paper, and adhesive. Cut a 4 by 5 piece of card stock. Score the card at 2 inches, 4 inches, 8 inches, and at 10 inches. Cut a slit from 2 inches down to 10 inches on both sides of the paper, setting it in about 1.5 inches from each side. Now, fold the card where it was scored. Cut your decorated paper to fit in the panels. Attach ribbon. Cut out a skull and cross bones and attach it with fishing line.
