Treble Crochet Video Tutorial
A treble crochet (sometimes called triple crochet) is taller than a double crochet and is made by working two yarn overs at the start of the stitch, instead of one yarn over as for double crochet. It is abbreviated tr.
Step 1
Yarn over twice, insert the hook into the work (fifth chain from hook on the starting chain).

Step 2
* Yarn over and draw yarn through, pulling up a loop.

Step 3
Yarn over again and pull yarn through the first two loops only on the hook.

Step 4
Yarn over again and pull yarn through the next two loops only on the hook.

Step 5
Yarn over again and pull yarn through the last two loops on the hook.

Step 6
One treble made. Yarn over twice, insert hook into next stitch; repeat from * in step 2.
