My sister dressed up as a stop sign a few years ago. All you need is two
pieces of thick board (such as foam board), an exacto knife (these can be
purchased in any art store), red and black spray paint, some sort of rope,
black leggings, a black long-sleeved shirt and black face paint.
Cut both boards into the shape of a stop sign (I can't remember how many
sides it has-sorry) with the exacto knife and spray one side of each boards
After this has dried, spray STOP with the black spray paint in the
center of each board. Cut two holes about 1 1/2 feet apart on each board
with the exacto knife. Connect the two boards with two short pieces of rope,
just long enough to hang over your shoulders.
When all of this has dried,
put on your black leggings and shirt, paint your face black and slip the
"stop sign" over your head.
Thanks to an anonymous submitter for this fun idea!!
