What is blo in crochet terms? Blo is a crochet abbreviation for back loop only.
When you crochet if you look at the top of the stitches you will see two strands of yarn that make a sideways v shape. Each strand forms a horizontal bar.
These are called loops. The back loop is the strand of yarn furthest away from you. The one closest is called the front loop.

BLO in Crochet Patterns
When a crochet pattern wants you to only work into the back loop of the stitch, it will be written as blo and then it’s usually paired with the specific stitch.
For example, sc blo means to work a single crochet in the back loop only. Typically, a single crochet, or any crochet stitch, is worked under both loops of a stitch.
Blo crochet is worked only under the back loop. And likewise, flo stitches are worked only under the front look.
Your crochet pattern may choose to a blo, or back loop only stitch pattern for a few reasons.
One common use of the blo stitch is for creating a crochet fabric that is stretchy. When you work into only one loop, it makes a looser, stretchy stitch that’s great for crochet hat ribbing and sleeve cuffs on a crochet cardigan.
Tip for crocheting ribbing-when you get to the end of the row, work under both loops so you’re edges are better defined.
Other than ribbing, using the back loop or front loop only in your crochet project gives you a different texture than working under both loops.
How to Crochet in the BLO
- To blo sc begin with a row of single crochet stitches.
- Look at the top of each stitch.
- Insert your crochet hook in the top of the stitch, and slide it under the back loop only.
- Then work your stitch as normal.
