Back Loop Only (BLO) — crochet stitch tutorial

Creates a crisp fold line — this is how a flat bag base turns up into a wall at a sharp 90°.

UK terminology: back loop only

How to work it

  1. Look at the top of the stitch: two loops form a V.
  2. Insert the hook under only the loop furthest from you.
  3. Complete the stitch as normal. A visible ridge forms on the front.
