Optical Art is all about using illusion to create bold works of art, and the Chevron Illusion sweater pays homage to that endeavor by using a chevron-inspired stitch pattern in two high-contrast colors to create a graphic Op Art-inspired drop-shoulder pullover. Instead of featuring the chevron design all over the body of the sweater, I’ve placed it just on the bracelet-length sleeves, which are worked without shaping to make them a little more bold and dramatic.
