How to Make a Cookie Monster Costume. Instead of dressing your child as a ghost, witch, power ranger or transformer on Halloween, add a little peace and happiness to the holiday with a Cookie Monster costume. Believe it or not, Cookie Monster is one of the easiest costumes to make. Consider the fact that Cookie Monster is really nothing but a big ball of blue fur.
Determine what type of body to make based on time constraints and sewing skills. If you can't sew at all, go the easy route and just wear a blue sweat suit or floor length fuzzy robe. If you can sew, whip up a pair of fuzzy blue body coveralls with a zipper or Velcro down a front opening to make it easy to get on and off. Either will make a great Cookie Monster costume.
Make Cookie Monster's eyes using big white stiff foam or hollow plastic balls. Cookie Monster's eyes are the most difficult part of this costume and will take the most time.
Gauge the size of the irises (black centers) in Cookie Monster's eyes by the size of the white balls you use and the size of your costume.
Look at a picture of Cookie Monster to guide you in making the eyes. Use black buttons or circles cut from black construction paper to make the centers of Cookie Monster's eyes. Once you determine the proper size, just hot glue the buttons or circles to the center of the white balls.
Glue the balls to the top of the hood so they rest on top of our head when the hood is up. If you chose to wear a robe or body suit, just attach the hood to the collar of your costume with a few stitches or seam tape.
Slip on some fuzzy blue house shoes or socks if you have them. If not, your tennis shoes will do fine. After all everyone will be looking at those great Cookie Monster eyes and will never notice your feet.
Paint your face blue and carry a cookie jar to add the finishing touches to your costume.
