Crochet ribbing (sc in back loop)

Single crochet in the back loop only. Stretchy, knit-look ridges.

#7 of 10 · Updated November 2026 · The Yarn Math

Crochet ribbing (sc in back loop), illustrated.

Working single crochet into the back loop only leaves the front loop as a horizontal ridge. Worked sideways, rows of these ridges look and stretch like knitted ribbing, which is why it is used for brims and cuffs.

How to make crochet ribbing (sc in back loop)

  1. Insert the hook under the back loop only of the stitch (the loop furthest from you).
  2. Yarn over and pull up a loop (2 loops on the hook).
  3. Yarn over and pull through both loops.

Pattern

  1. Chain the length of the brim or cuff you want (it becomes the height of the ribbing) + 1.
  2. Row 1: sc in the 2nd chain from the hook and in each chain across.
  3. Row 2: ch 1, turn, sc in the back loop only of each stitch across.
  4. Repeat row 2 until the ribbing is long enough to go around, then join the ends.

    Questions

    Why is my crochet ribbing not stretchy?

    Make sure you are working through the back loop only on every row, and try a hook one size larger.
