March 21, 2024: This pattern has been updated with instructions on how to make a lighter, short-sleeve version!

The Geometer sweater is a circular yoke sweater with sweet details like overall colourwork and corrugated hems and cuffs. It’s worked seamlessly from the top down and the geometric pattern across the yoke is an evolution of the pattern on the Geometer cowl. Just as the cowl, the Geometer sweater uses Spincycle Dyed in the Wool as contrast for a gorgeous colour-shifting effect.
