One key discipline I’ve learned over the years is to design with my arm and draw with my wrist. There’s a dynamic balance of freedom and control in my wrist, and a dynamic balance of freedom and control in finding the right design language when the arm is moving loosely. When I become lazy and miss the arm out, the artwork tends to be static and lifeless. These images (left) are from a 90-minute demo process in a live workshop. The 18x24-inch canvas gave me a good amount of arm flexibility. Then I took a hi-res iPhone photo and transferred the file into Photoshop for value and colour.
