In this tutorial, we learn how to crochet a round shell Catherine's Wheel left-handed. For the first round you will start by doing four single crochets after the slip stitch. After this, do seven double crochets, then a single crochet followed by seven more double crochets. Make two more chain stitches, then a single crochet and three double crochets. After this, start the next row which will be a chain stitch, then three double crochets. Next, you will do seven double crochets, followed by a chain stitch and single crochet. Continue this pattern until you have a wheel as large as you want it to be. Tie off at the end and your creation will be finished.
