Back when my eyes were sharper and my hand steadier, I would make hand drawn greeting cards for kin and friends. They were well received and requests for cards were taking up all my spare time. People would approach me at work and want me to draw up a card, spur of the moment. I explained I can't draw from memory very well. The way I worked was to collect as many cartoon strips and comic books as I could. Then, I would find a cartoon character or other in a pose I needed, re-draw the character to the size I needed, add other details such as scenery etc, and color with felt tip markers. Not all my cards were cartoon characters but they seemed to be the most popular. I was experimenting with 3-D pictures, but quit to pursue other interests.
