Here is an easy crochet pattern for a Quick Lattice Cardigan. It’s done with worsted weight yarn (size 4) and a large crochet hook (size P - 11.5mm) and can be finished in a day.

The cardigan is crocheted from side to side in one piece. Stitches used are chain, slip stitch, single crochet and double crochet. You will need two skeins of aran/worsted weight yarn, a size P (11.5) crochet hook, and a yarn needle for weaving in the ends when you are finished. Make sure your hook is the correct size P (some P hooks are 10mm, this one needs to be 11.5mm). I recommend Lion Brand Cotton-Ease or Hobby Lobby’s I Love This Cotton as great yarns for this project.

The cardigan can be made in size small, medium, large and extra large. It makes a great layer over a tank, a t-shirt or a dress. Perfect for spring and summer!

Finished measurements when closed:
Small - Chest 32”, Length 18 1/2”
Medium - Chest 36”, Length 19”
Large - Chest 40”, Length 19 1’2”
Extra-Large - Chest 44”, Length 20”
The Cardigan is meant to be worn open and has lots of stretch, so choose size according. For instance, a woman with a 38” chest could wear the medium size. You might want to go down a size.
