Crochet Diamond Cardigan Pattern For Fancy Layerings

Diamond Cardigan Pattern

The Crochet Diamond Cardigan Pattern is a really simple and fun thing to make for warmer days. You start with just a rectangle shape, which is nice because it’s easy to do. This cardigan is big and comfy and has a pretty design with little holes in it that make it cool and airy to wear when it’s hot out. You can wear this cardigan in lots of ways, like over your summer clothes, as a fancy coverup for the beach, or even when it’s a bit chilly in the spring or fall. The crochet beach wearable pattern tells you how to make it in many sizes, from very small to very big, so anyone can make one that fits just right and looks good. So, choose the color you want and start crocheting!

Step by step Pattern

Starting Guide & Gauge Swatch

  1. To begin, chain 2. Insert the hook into the 2nd chain from the hook. Yarn over, and pull up a loop. Yarn over, and pull through one loop on the hook (one chain made). Yarn over, and pull through both remaining loops on the hook.
  2. For all the following stitches: Turn work upside-down so the bottom (foundation) edge is facing you. On the bottom of the previous stitch, there is what looks like the top of a normal crochet stitch (the chain from the previous stitch). Insert hook into both strands of that “stitch”. Yarn over, and pull up a loop. Yarn over, and pull through one loop on the hook (chain made). Yarn over, and pull through both remaining loops on the hook.
  3. Chainless Starting Double Crochet: (video tutorial here)
    • Stretch loop on the hook until it is slightly longer than a regular double crochet. Holding the top of the loop still with your finger, yarn over with the stretched loop on your hook (not the working yarn) 1 time. Insert the hook into the specified stitch. Yarn over, and pull up a loop of yarn. (Yarn over, pull through 2 loops on hook) 2 times.
