Fasten off (FO)

How you finish a piece of crochet so it cannot unravel.

What is fasten off?

How you finish a piece of crochet so it cannot unravel. You cut the yarn and pull the end through the last loop.

In a pattern you will see it written as FO in both US and UK patterns.

How to do it, step by step

  1. Cut the yarn, leaving a 6 in / 15 cm tail.
  2. Yarn over and pull the tail all the way through the loop on your hook.
  3. Pull snug to lock it.

The mistake to watch for

Cutting the tail short leaves nothing to weave in. Six inches is a safe minimum.

If you are left-handed

Hold the hook in your left hand and the yarn in your right. Work rows from left to right, and read any chart diagram as a mirror image.
