The M was made by outlining the letter shape with an Expo Vis-A-Vis Wet Erase marker. Then spritz with water and watch the magic. The N was written with Dr. Martins Bleedproof White diluted with distilled water to a happy writing consistency. The O is the Walnut Ink Lift trick: spread some Walnut Ink on watercolor paper and leave to dry. Then write the letter with water and blot to reveal. The P was written using Winsor Newton Calligraphy Inks (blue cap) Dark Blue and Yellow Ochre. These inks are intense and lightfast.
