Slice cardboard into long, uneven strip, about 33-5 inches wide. Slight angles give a more realistic boarded-up look.
Use your own hand or print a stencil to trace several reaching hand shapes on black paper or painted cardboard. Then cut them out carefully.
Tape or glue the hands to your window glass or wall first, positioning them at various angles for movement.
Layer the cardboard strips diagonally across the window, overlapping slightly as if nailed in place. Secure with tape or removable adhesive.
Bend or tear the edges of the cardboard slightly to make it look aged and weathered.
