The kids are so enamored with the comics I make in Comic Life 2 that I thought I would show them how I do it. They loved it. Sitting on the couch, curled up next to me, we went through the whole procedure. We took the pictures with Photo Booth and dragged the pictures into the Comic Life 2 template. The kids each had their own ideas about the colors and shape of the borders, and the comic reflects ALL of their inputs. He wanted green. She wanted pink. So its all pink and green. Both of them wanted to sound like dinosaurs.
No actual tutorial here; the program is so great, you would find the process self explanatory. Before long, they will be making their own comics.
