Lacy and Open-Stitch Summer Cardigans

These open-stitch designs let the breeze in while still giving you that cozy, layered feeling. Each of these patterns uses lace stitches or openwork mesh to create a cardigan that’s as airy as a summer evening.

June Summer Cardigan Crochet Pattern by Knitting with Chopsticks

The June Summer Cardigan is a gorgeous lacy coverup worked in an open mesh stitch that makes it feel as breezy as the season itself. It’s designed as a longline beach coverup that works just as beautifully over a tank top or swimsuit as it does over a summer dress.

Worked in two lengthwise panels that are folded and seamed, this one comes together more quickly than you might expect, and the simple stitch repeat makes it a great project to pick up and put down.
