Back in the old days while in high school (when we walked to school barefoot in the snow - by bus), I and another art student stumbled into doing dungaree jacket paintings for a while. Anyone interested was always willing to pay 'something' for the work involved. The work was frustrating and time consuming, but it was always gratifying to their love of the work and to receive compensation was an added bonus. Be optimistic and subtly remind them that art, whether on canvas or computer, is work requiring skill and time. BYS
