LOUISVILLE, Ky. (WDRB) -- It began as something to keep her busy on those long car rides she took as a child. Then it became a hobby. Now,  Carrie Johns is hoping an Etch-a-Sketch can become her new-found source of income.

"You have to be very careful because if you mess up , you gotta start all over again. There's not a whole lot of room for mistakes," Johns said. "I think it's a really neat feeling to see people react to someone who can draw on an Etch-a-Sketch."

Johns, who lives in east Louisville with her husband and two children, is a commercial artist whose often paintings or drawings are often sold at auctions. Some of her drawings on an Etch-a-Sketch can take her months to complete. She's drawn the Roman Colosseum, Rick Pitino and the National Champion Louisville Cardinals, along with horses around the historic first turn at Churchill Downs.

Johns is modest about her skill. Those who buy her art gush over it.

"I was just in awe of how detailed and beautiful they were," said Candy Bennett, whose husband Steve had Johns make graphite portraits of the Bennett's children. "I wish were able to do something like that."

By using an Etch-a-Sketch, Johns' art - in a way - is already pre-framed by red plastic.

"Somebody asked me once if I could do a picture for them and I did - it just has been something I was able to do," Johns said.

Carrie Johns prefers to start the needle in the middle of the Etch-a-Sketch and work her way out, using the cursor and the aluminum dust inside to create drawings that surprise many who see them. 

"I would say that doing Etch-a-Sketch stuff is almost kinda like doing tattoo - you can't take it away. It's there," said Johns.

It's there - unless you drop it. Then Johns might be able to fix it. But she might not, meaning you've either lost the art or could be forced to pay for it twice.

Johns jokes: "Maybe you shouldn't be so careful with it. If you drop it maybe I can do another one."

Johns says she is booked up through February and has been commissioned to do a couple of oil paintings and three more Etch-a-Sketch drawings.
