Debbie Clapper is a Boulder-based artist, muralist, [recovering] designer and mentor.

Drawing nearly every day since the age of 9, she has mastered the art of freehand drawing and painting without the aid of a ruler or straight edge. She has built a lush career around pattern illustration via her passion for abstract optical illusion art. Her funky yet sophisticated designs have brought life to brands such as Smartwool, Rickshaw Bags and Pactimo.
