Sari asks: Do you draw a lot?

Yes, I do draw a lot. I draw in my sketchbook every day and do a lot of practice drawing. That's how you get better!
Here is a drawing I did at a diner....

Karin wants to know: What exactly is a sketch?

A sketch is a quick practice piece for the finished piece of art. It lets you see how certain things look before you go through the time and effort of a whole finished piece of art. A sketch may be done with a pencil, pen, watercolors, crayons- anything. Below is a pen drawing sketch I did for the page in PAINTER AND UGLY in which the two dogs meet again during the race.
