Gold puff paint has been my latest "Go to" medium of choice, especially on a dark background. It looks sort of regal when illustrating natural backgrounds like bullrushes emerging from a swamp. This provides a suitable setting for frogs, dragonflies, and concentric rings that often occur when dropping a pebble into a pond. These composed scenes remind me of what it is like to get out of town and venture off into different settings and find quiet, peaceful surroundings where surprising little critters abound.
Painting on panels of wood has provided me with a more preferable surface than the small canvases purchased at the dollar store. Although these aren't rocks, a small format invites one to experiment more than a large canvas which can be a bit intimidating. With time being of the essence, it's a bit easier to paint over a rock after some mishap, than sanding and painting over a mistake made on a large canvas. The rock, however, has many more opportunities for display than even a small canvas
