Stitch Overview


This stitch lends a little bit of texture and stretch. I think that the texture is a bit more interesting than a simple single crochet ribbed stitch. It seems to lay flatter than a single crochet rib as well.


  • lays flat (not ‘corrugated’ like a single crochet rib) making the stitch good for the edges of garments.
  • fun texture to work with & look at (in my opinion)


  • chaining 2 at the beginning of each row leaves an unsightly gap
  • slip stitch rows can sometimes be more difficult to keep track of

Let me know if you have any questions about this pattern, or if you’d like to see a particular type of crochet ribbing explained!

Happy Crocheting!
