To make a Garfield comic, start by imagining a unique situation for Garfield. Decide on the layout and panel sequence. Use simple but expressive drawing styles. And don't forget to include Garfield's trademark humor and laziness!
First, you need to have a good understanding of Garfield's character and personality. Then, come up with a funny or interesting storyline. Sketch the characters and settings, and add dialogues to make it engaging.
