What is a Crochet Back Loop?

The front loop and back loop of a stitch is the top of a stitch that you work into when crocheting. There is a front loop and back loop of every stitch, which resembles the letter “V“.

The back loop is the part of the V that is furthest away from you when crocheting. The front loop is the part of the V that is closest to you when crocheting.

Understanding Crochet Abbreviations for BL

In crochet patterns, using this technique, you may see the back loop abbreviated or referred to as bl crochet (back loop) or blo crochet (back loop only). The same goes for front loop only stitches when they are abbreviated in patterns.

The Yarn & Crochet Hook

When you are first learning to crochet though the back loops, the best thing to do is to practice with a swatch or a small sample.

First you will want to get your yarn ready, which preferably should be a medium weight #4 yarn for new crocheters (it is easier to work with) and a corresponding crochet hook to go with your yarn.

Vanna’s Choice by Lion Brand is an easy to find four weight yarn and pairs well with a 5.5 mm or 6 mm crochet hook for this crochet project.
