Gauge after blocking: 18 sts in diamond network pattern = 3” (7.5 cm).

From the pattern:
Complete with body shaping and fully fashoned decreases at the neckline, Kathy Zimmerman’s cabled vest is inspired by the 1920s flapper-style tennis vest, reminiscent ofThe Great Gatsby* look. Stitches along the side seams are worked in reverse stockinette stitch so the body shaping does not interrupt the cable pattern. The back and front are worked separately; the neckband is worked simultaneously with the front. The armbands are finished with a cabled rib.*
