What it looks like in a chart
A long vertical post with a bar across the top and three diagonal slashes on the stem. It is the next rung above treble crochet, and the slashes are the count: no slash is half double, one is double, two is treble, three is double treble.
Each slash stands for one of the three yarn overs you make before inserting the hook, so the symbol is a literal picture of how the stitch is built. On a chart it is unmistakable — nothing else in the standard set is that tall.
How it is used
- Very open lace, where a few long stitches and long chain arcs cover a lot of fabric.
- The long spokes of a doily or snowflake, reaching from one round to the next in a single stitch.
- Deep scallops and points on an edging, where neighboring stitches step up from dc to tr to dtr and back down.
Worth knowing
UK patterns call this a triple treble (trtr), one step up the ladder as usual. Be careful with that name: trtr is on both lists and means a different stitch on each. A UK trtr is what a US pattern calls dtr, while a US pattern using trtr means the stitch one rung higher again.
A stitch this tall is loose by nature. Many patterns pair it with shorter stitches on either side so the fabric does not sag — and on a chart you can see that stepping pattern immediately.
Common questions
What is the tall symbol with three slashes on a crochet chart?
A double treble crochet (dtr) in US terms, which UK patterns call a triple treble (trtr). Three diagonal slashes on a long post, one for each of the three yarn overs the stitch takes.
What is the difference between treble and double treble crochet?
One yarn over. A US treble takes two yarn overs and is drawn with two slashes; a double treble takes three and is drawn with three, and comes out taller. In UK terms the same pair is called double treble and triple treble.
