Hello, my name is Debbie Clapper,
and I'm a doodle addict. Greater Cleveland Area

Drawing nearly every day since the age of 9, I have mastered the art of freehand drawing and painting without the aid of a ruler or straight edge. I have built a lush career around pattern illustration via my passion for abstract optical illusion art. Heavily inspired by M.C. Escher and graffiti, my work strives to inspire and ignite imagination in all who interact with it. Over the last 19+ years, my funky yet sophisticated designs have brought life to brands such as Smartwool, BOA Technology, Hope Hummus, Rickshaw Bags and Pactimo.

I specialize in black white line, doodling, drawing, graphic design, illustration, murals, patterns, pen and ink, typography.
