If you were to take a narrow old belt or some non fraying piece of fabric(felt?), the length of his cir. of his head, you can then use dots of Tulip ,or other fabric paint in a tube and make dots of paint in a pattern. Stick to 5 to 7 dots across the width of the piece, and use simple shapes. An arrow, zig-zag, etc. It won't be very authentic, but it will be quick, cheap and easy.
Felt-$1 +/-, 5 colors of fabric paint, white, black, red, yellow, blue/or green- a package is about $3 at
walmart, or 86 cents each for some brands. and then feathers? A.C.Moore had a package of bright color quills for $1 yesterday.
Hope this helps, best of luck.
