Calculus is the mathematical study of change, used in every branch of science and life. Drawing from the wondrous world of mathematics has been the inspiration behind the Calculus Collection by James Dunlop.

From small scale lineal upholstery patterns, geometric draperies and round off with a soft, muted sheer, this collection is very concise. The colour palette is broad, with strength being given to the designs with additions of rich red, ocean blues and dramatic black.
