Creating Tribal Designs

This is a method i taught myself after seeing this kind of design on my ex-girlfriends sweatshirt. i think it is pretty cool and i hope that you do too. let me know if you have any suggestions or ideas.

*Update* For all the people asking for a photoshop verson of this tutorial i am downloading a trial version of photoshop and working on it tonight so expect it in 2 to 3 days. thanks to maverick101 [link] for finding the trial version for me.
