Another 2.5x3.5 Artist Proof card in Copic marker. I'm not quite sure why a company producing so many sketch cards would use such an unfriendly card stock. The grainy-elements to the art are a combination of the printing and the lower quality paper components mixed in that resist the ink from the markers.
I'd considered buying some 1-ply Strathmore Bristol to bond to the surface of the card and using an artist quality mounting fluid to bind that to the card. With the wonders of Photoshop I could have even printed the various graphic elements onto the bristol so the only difference would be the thickness of the card.
I decided to soldier on and see what I could do with the cards as is, though, knowing I could fall back on that if this went pear-shaped.
