Back Loop Treble Crochet Abbreviations

The back loop treble crochet is abbreviated BLtr or BLO tr in crochet patterns.

Learn more about crochet abbreviations & find a complete list on our Crochet Abbreviations & Terms post.

BLtr Chart Symbol

The back loop treble crochet chart symbol is related to the treble crochet (tr) stitch chart symbol.

It is a “T” with two lines across it representing the 2 yarn overs you do, like the regular treble crochet stitch. However, it also has a half circle below it pointing downwards representing that it’s worked into the back loop only.

It will be turned in the direction it will lay in your finished crochet work.
