Mitered squares continue to fascinate me. The color, design, and various possibilities are endless. The squares remind me of a baseball field and my kids sliding into “home plate.” The mitered squares are worked individually picking up stitches as you work a series of columns. Changing colors create interest and a fun knitting experience. Upon reaching the end of the blanket stitches are again picked up to create a border. This project is seamless.

Errata: page 8: 2nd columnInstead of picking up sts from the right you will pick up from the LEFT of each mitered square!
