V-Stitch Summer Cardigan
This cardigan from MJ's Off The Hook Designs is built around a simple, airy V-stitch that works up quickly and keeps the fabric light enough for warm weather. The pattern comes in two versions, a chic three-quarter sleeve tie front cardigan and a longer variation with full length sleeves and a ribbed edge, so you can pick the look that fits your wardrobe.
It is written in sizes XS through 5X, with bust measurements from 28 inches all the way to 62 inches, which makes it one of the more size inclusive garment patterns you will find for free.
