My 11-year-old niece Ashley is visiting for a short week of art camp. Yesterday we got out all the Zig markers — and I’ve got a slew of ’em: writers, calligraphy, brush-and-scroll — and spent half the day playing around with them. Here’s my experiment, on Fabriano cold-pressed watercolor paper. The bamboo comes out of a booklet, Color Layering System, by Suzy Ratto. The rather strange column of lettering is based on one of Hans Joachim Burgert’s pieces.
