Lab Coat?

[maybeabumblebee.livejournal.com]

Ok. My girlfriend is in O-Chem (silly chem majors) and has to wear a lab coat like this one.
She wants me to help her decorate/dye it.
Any ideas? I know I'm going to stencil it, but i also want to make it not-white.
It's 65% Dacron and 35% Cotton....
Will it not take dye? Any suggestions for a certian dye or process to change the color?

Also, does anyone know where I can get a stencil of hanfcuffs for another chemistry related shirt I'm making her? (Chemistry is all about Bondage.)<= it's funny because it's true.

Thank you and sorry for the text only.
I will def. post a picture when it's done though.
