Playing with the air brush on an old T-shirt

This picture is back from July 2008. Unfortunately I have not played with it again since.... yet

There were a whole lot of those Mexican type skulls around at the time and I really liked all the colours.
Apparently you should use a textile medium first like an undercoat to get the airbrush to stay?
It's an old shirt and I was just playing around. I will have to look more into it next time though.

See how it looks dull in the picture.. it looks even dull-ER in real life.
I did iron it on though and it didn't wash out... probably because it was already washed out to begin with hehe
