Highlighters are useful for marking important information in school textbooks---and you can dress as one if you need an innovative and unusual Halloween costume. You'll need a few basic items to transform yourself into a highlighter marker. Most highlighters are neon yellow, pink, orange or green. Get together with a group of friends to become a pack of highlighter markers.
Cut out the bottom of a canvas laundry bag. Take it outdoors and spray paint it yellow. You can use pink or neon green instead of yellow, if you prefer. Allow the paint to dry for one hour. Check to see if the bag needs another coat of paint. Add enough coats to colour all of the visible bag fibres.
Cut a rectangular strip of poster board. Twist the poster board into a cone shape. Make the base of the cone large enough to fit over your head. Tape the sides of the cone together. Punch two holes on opposite sides of the cone. Tie a piece of elastic to both sides of the cone to make a chin strap.
Cut out the word "Highlighter" from black felt. Glue or sew the letters to the front or side of the laundry bag.
Put on yellow tights and a yellow shirt. Pull the laundry bag up over your body and tie it in place just under your armpits. Wear yellow shoes, if possible. If you do not have yellow shoes, you can put on yellow socks and use the socks as shoes for the day.
Paint your face with yellow face paint, if desired, to transform yourself into a complete highlighter.
