Hye-Sung standing next to the paper that we needed to color. For reference, Hye-Sung is about 5'1" - she attempted to calculate her height in feet/inches (she knows her height in centimeters) and then told me that she was ten feet tall. I laughed and told her that the panorama was twelve feet long. She yelped in surprise and admitted that she may have made a mistake in her calculations.
Hye-Sung mixed up this huge tub of watered-down acrylic paint, in which we would briefly dip the paper. Easier said than done: Japanese paper is very strong but very thin. The tray wasn't big enough to float the paper in, so she held one end, I held the other, and we sort of 'rolled' the paper through the paint.
We rigged this drying device so that the paper would hang to dry. If we dried the paper flat against a table, the watery paint would pool and cause streaks of color.
