We are having a new exchange of 4"x6" art in my LMA group and this is the painting I did. It's already been received so I'm not blowing the surprise by posting it here. This is the size that would be called an OSWOA if the art were sold but I don't know what to call it since it's an exchange!
Hold on to your hat as it will surprise you to learn that this was done in colored pencil! Yes, I know - not my favorite medium but I wanted to try out the ColourFix primer on matboard and thought this cup of coffee would be a suitable subject with which to experiment. The ColourFix is the same primer that I used to salvage that awful Tiziano paper that I'd bought on sale.
This painting used a variety of colored pencil brands and the support is acid-free mat board. I applied the primer with a small paint roller and that seems to have worked well. I don't claim to be any great shakes at still life painting but this came out pretty well if I do say so myself. Of course, I always see things that could be improved but I doubt if I ever get over that and actually hope I don't!
