Cornerstone Squares, with their ch-1 corner stitches and back-loop-only rounds, make a geometrically elegant, repeated-squares design, as well as show a subtle X etched through each square. A faint hint of folding emphasizes the corner-to-corner X in the squares, and provides intriguing visual appeal when the squares are joined together.

The Cornerstone Square Hat is made with three squares that are joined in a circle, then capped with rows of double crochet.

Cornerstone Square Projects are available a la carte, or as a pattern book containing all seven projects.
