I used Bienfang Graphics 360 Marker Paper, 12x9, and Rembrandt burnt umber thinned with a little medium that was a mixture of linseed oil/OMS in about a 60/40 ratio.
The description of the paper is "Graphics 360 is a 100% rag, non-bleeding, translucent marker paper. It retains true color with permanent as well as watercolor markers." I think the paper is considered archival but not sure if the oil paint will have an affect on how archival the piece will be. More research needed.
I really liked the way it handled. The wetness soaked into the paper slow enough that I was able to rub out some forms, yet the paper did not buckle. I've used canvas paper before and it was too thirsty. It soaked in so fast that the rubbing out did not work well.
If I decide to finish these off I'll matt them and frame like a drawing.
I plan to experiment with the new arches oil painting paper and find some vellums to try. If you have anything you like to work on let me know. I'm looking for something not too expensive since coming up with a winner while speed painting 2-5 minute gestures poses is hit or miss.
