This is a good method to use for casting off a ribbing stitch.
For all purl stitches, cast off purlwise:
- Bring your yarn to the front and purl the first purl stitch, then pass the first stitch over that second.
- For the next purl stitch, cast off purlwise again.
- With your yarn in the front, purl the stitch then pass the first stitch over that second.
