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.

⚡Flash Back Friday⚡ Going back to a blackbook doodle from a few years ago. Why am I showing you this? Because graffiti art is, and has been, one of my greatest influences (aside from M.C. Escher). It is an art form I love, and I gain much inspiration from the graffiti scene (legal and illegal). I don’t really show this side of my art to the world, but it is fun for me to create, and it definitely informs my other pieces of work.

Swirly doodly pattern study time!

Freehand study of optical illusion cube pattern.

Geometric pattern doodle - all freehand! Markers used: Posca Pens

Getting more detailed with this pattern study, so this definitely wasn't a quickie! Gold Posca pen stream of consciousness doodling.

Getting weird with pattern rules on this one!

Overlaying patterns. Organic vs geometric.

This sketchbook is all about triangle patterns! Each page starts with a base layer of connecting triangles. From there, I fill in different patterns on each page, challenging myself to come up with new ideas for each page.
