Drawing with paint
Next, I have to replace the charcoal lines with paint lines. I don't want to mix the charcoal with the paint, so I very carefully wipe away a small segment of charcoal and quickly replace the line with paint. For this drawing, I am using a number 2 Monarch brush with burnt sienna and a little Liquin.
My rag is a piece of an old cotton knit shirt. I prefer the cotton fabric to paper towels as it is much more absorbent and I can use one rag for hours. It's easier on the trees too.
