Art Notes: This painting was painted over a failed painting that my husband sanded down. Sanding leaves the surface smooth. Depending on the amount of sanding, it can leave ghost images of the previous paintings, or a soft mid-tone background. This one had a soft beige background. I wanted the butterfly to be loosely painted. I mixed a transparent black (alizarin crimson and winsor (Pthalo) green) for the body and lifted out the spaces for the colors with gambol on a Q-tip.
