Brush, ink and bare paper
Zen Ink
Ink painting from Japan's Zen temples, and from the workshops that carried it on. Mountains left half in mist, gibbons in the trees, a cat asleep on bare paper, Bodhidharma looking straight back at you. Sesshū, Sesson, Hakuin and the monks around them worked almost entirely in black, and left most of the sheet alone.
As a puzzle
The quietest and the hardest table here. A few dark strokes carry the whole picture, so you build outward from the ink and then feel your way across the empty paper. Most are tall hanging scrolls. Keep the count low and let it have the whole evening.
A good size here: 40–120 pieces.
