i wouldnt advise using sharpies, thier ink reflects an undesireable copper-ish reflection when light hits it, and doesnt look good at all. i know this from experience [img]i/expressions/face-icon-small-sad.gif[/img]

id say either wait til you can get more markers, or try and use some testors flat black with a really fine brush. maybe have a rag handy with a little bit of thinner on it to fix mistakes hehe
