Fold a few origami skulls to use as Halloween greeting cards, party invitations or inexpensive, simple holiday decorations. If you're new to origami, or paper folding, a skull is an ideal way to start as it is less complicated than other origami techniques. The project is simple enough for young children to try as well. Once folded, decorate the skull however you wish with markers or paint. Use square paper to make the skull or cut 8.5-by-11-inch paper into a square shape.
Lay a piece of square paper on a work surface. Fold the paper in half to form a triangle. Press on the fold to make a crease. Unfold the paper so that it is square again.
Fold the paper the other direction to make another triangle. Press on the fold to crease, then unfold. Tilt the square so that it is in the shape of a diamond. You should have two creases on the paper that form a plus sign across the diamond shape.
Fold the two lower sides of the diamond in so that they meet along the center, vertical crease. The paper should now be in the shape of a kite.
Fold the top point of the kite shape down about 1 inch from the top.
Fold the bottom point of the kite shape up, making a crease about 3 inches from the bottom. Fold the point down again, about 1/2 inch above the first crease, making another crease.
Flip the paper over so that the folded parts are on the back side. You should have something that resembles an ice cream cone with a single scoop of ice cream on top.
Fold the bottom point of the paper up toward the "ice cream scoop," making a crease about 1/2 inch below the bottom of the "ice cream scoop." Fold the point so that it points downward again. Fold it up again, and fold it down once more. You should now have a shape that looks like a skull with a row of teeth below.
Draw eye sockets and nostril sockets on the skull. Decorate the skull however you wish with markers, paint or other crafty supplies.
