Willow charcoal is ideal for sketching on canvas prior to painting. The absence of a binder agent makes it easy to erase. Unlike heavily compressed charcoal, willow charcoal is light and so produces soft, powdery lines. Blend using blending stomps or tortillons as oils on your hand can darken the charcoal and create a mess.
