These black and white drawings are exciting to see, and were a joy for me to do freehandÑwithout pencil, directly in pen on paper. You can join in that experience by coloring them with gel pens, brush- or hard-tipped markers, oil crayons, or anything you enjoy using.
Coloring is a creative act that enables focus, concentration, and awareness of the moment, without worry about there being a right result. If you don't stay within the lines, that's fine.
Coloring is a way to enter a mindful mindlessness, a conscious relaxation while enjoying the visual sensuality of color.
