Thanks so much Prism99 for your reply. I was a bit apprehensive about the oil Sharpee as I saw it under fabric listings, as I only saw comments about it in metal applications. So the Sharpee is out.
I'll look into the Shiva Paint sticks. I have seen them used in a demonstration before, but only in metallics. I see there is a matte finish also. After further investigation on the internet I found they can be used a with a brush with or without a stencil.
Thanks so much for your help!
