Crocheting the Ribbing and Cuffs

- Chain 2 and turn your work
- Insert the hook into the back loop only of the second stitch to begin the next row
- Continue working half double crochet back loop only across
- Work a normal half double crochet through both loops for the last stitch
- Repeat rows until the ribbing reaches the needed length for bottom edge, cuffs, and front edges

Joining the Squares
- Align squares with the bad sides facing the same way
- Cut yarn twice the length of the squares and thread a needle
- Insert the needle through both corner stitches and tie securely
- Take one side loop from each square and sew them together
- Repeat until reaching the end
- Flip squares and weave the needle through stitches to secure the end
- Follow layout to form the back panel, front panels, and sleeves

Joining Ribbing to Cardigan
- Use the same sewing method to attach the bottom ribbing to the main body
- Sew the front ribbing along both front edges by taking one loop from ribbing and one loop from the squares
Attaching the Cuffs
- Fold the cuff and sew the short ends together to form a loop
- Tie the beginning of the cuff to the sleeve edge
- Sew using a ratio of three or four loops from the sleeve to one loop from the cuff
- Continue sewing around the sleeve opening and secure the yarn
- Repeat for the second sleeve
