I just completed 4 minis on 5 x 5 canvas. I prefer gallery canvas. It gives you an extra 1 1/2 inches to continue the painting on all four sides. I usually paint the sides black but I like to wrap the painting around every once in a while, especially on mini-paintings. So in order to get the full view you have to see the sides as well (below)!
Like a wild animal, the soul is tough, resilient, resourceful, savvy, and self-sufficient: it knows how to survive in hard places. A quote by Parker J. Palmer
