Items you will need: (Hit your return key to start a new line)
* Bridal wreath style headpiece painted black or green
* Lots and lots of various sized rubber snakes - glow in the dark, etc.. I used over 4 dozen (Don't get too many that are heavy and too long)
* Heavy duty thread and needle
* Long Black dress from previous witch style costume or tattered style Greek goddess costume
* Makeup to make skin green and snake-like
* Old doll - Barbie with ruined hair works great
* 1 can of spray paint - the kind that turns sprayed item into stone
* Snake accessories - belt, earrings, fangs, etc...

Instructions:
Sew snakes to headband. Attach by securing the snakes tails, heads and body to headband using heavy thread. Pierce the snake' body and sew securely to the headband. Make sure snakes are of various lengths and that some hang down and some stick up. The more the better.

Fit headband to head. Adjust if necessary.

For the dress, either shred the hem and sleeves of an old long black dress or make a greek goddess costume look very tattered. Wear Greek style jewelry if desired.

Spray paint old doll to look like stone - since Medusa turned everyone that looked at her into stone. Either a Barbie or another doll with rigid arms and legs works well.

Paint face to resemble snake. Green skin, black around eys, bright red mouth. Many makeup kits have instructions for this.

Other information to consider:
Reference mythology books for pictures of Medusa and the story behind her for more ideas on what she looked like.
