- Position the 2 pieces together with right sides facing (for a wrong side seam) or wrong sides together (for a right side seam). Make sure the stitches across each edge match.
- Working through the double thickness of both pieces and using the same size crochet hook that you used in the design, insert your hook through the back 2 loops of the first 2 stitches, leaving a yarn tail about 6 inches long.
The figure shows the correct positioning of the hook in the back loops.
- Yarn over the hook (yo).
- Pull the yarn through and repeat Steps 2 and 3 in each stitch across; fasten off and weave in the ends. Take a look at the completed ridged seam here.
