My first card was doneas a joke, it was two fossil creatures and a joke about how old we were. (We were like 30 at the time.) But it was well received and so I kept doing it. Soon people were looking forward to my cards. Over the years I've progressed from hand drawn and inked images that I laid up by hand and photocopied at Kinkos, to computer graphics that I printed at home, to 3D images, to high level drawing and painting programs on a tablet. My abilities have improved with the technology.
