A friend of mine recently brought the idea of extending card art on trading cards to my attention... and it seems like a reasonably interesting project... I've played around with one or two already and am improving my techniques enough to start thinking of opening commissions for them in my local area (certainly magic cards will attract some interest)
My only issue at the moment is paints, I need to use acrylics in order to get reasonable coverage on the card, but the drying times on my acrylics are far too fast to blend with. So I was wondering if anyone has come across any thinner (or smoother), slower drying acrylics with the same coverage as normal ones?
