Fold the fabric in half and drape it over your child's head to form a hood. Mark where the layers meet under the chin. Extend the fabric down until it overlaps near the armpits on both sides, then mark those points.
Sew snaps at the three marked points on both sides for a secure fit.
Have your child try on the cape and mark where the elbows align. Carefully cut slits at each elbow for arm access.
Cut irregular slits along the bottom hem for a jagged, ghostly edge. Shorten the hemline if desired for the perfect length.
Apply white face paint to cover the face, leaving exaggerated hollows around the eyes for a haunting effect.
Fill in around the eyes with black eyeshadow to deepen the shadows and enhance the eerie look.
Dress in all black, don the ghostly cloak, and let the Halloween haunting begin!
