- Lay the 2 pieces to be joined side by side on a flat surface, with right sides facing up (for a right side seam) or wrong sides facing up (for a wrong side seam).
Check that the stitches across each edge match before moving on.
- Working in the top loops of the stitches only and using the same size crochet hook you used in the design, insert your hook through the loops of the first 2 stitches, leaving a yarn tail several inches long.
The figure shows the correct positioning of the hook in the loops.
- Yarn over the hook (yo).
- Pull the yarn through the loops and repeat Steps 2 and 3 in each stitch across. Fasten off and weave in the ends. This figure shows you what a completed flat seam should look like.
