10 X 10 Canvas...
Decided to go big, and learned a few things working on canvas. First, it is rough, so I don't use your "best" pens. Secondly, the larger the pattern the better - it is hard to try and do too much small detail. You can, however, still shade and get depth on the piece. To shade, I used a regular #2 rather than the softer graphite pencil, and an older "snubber" as the canvas sort of ate the point.
|I carried the patterns around the edges as I was not planning to frame this.|
I couldn't decide if I wanted to shade or not ... once I made the decision, there would be no turning back on canvas. You can erase on canvas, bit not very cleanly ... I like the depth you can achieve with shading, so ...
