Fold the fabric in half and drape it around your child's head creating a hood, marking where the two pieces meet under the chin. Wrap the fabric until it overlaps both sides near the armpits and mark the connections.
Sew snaps on both sides of the three points you marked.
Try on your child's cape and mark where the elbows fall. Cut slits in each elbow for arm holes.
Cut slits at the bottom to create a more jagged look. You can also make the background shorter if needed.
Paint the ghost's face with white paint, leaving large holes around the eyes.
Fill in around the eyes with black eyeshadow.
Dress in all black, put on your ghostly cloak and chase the night!
