Treble Crochet Stitch
Step 1: Chain 4
As we've already touched on how to work crochet stitches into a foundation chain, we're skipping to working this stitch into a regular crochet stitch. The Treble Stitch requires 4 chain stitches to begin each row, which counts as the first treble stitch of the row. This means when you're working this stitch flat, you'll always chain 4 stitches before proceeding to the rest of the row, and this includes the foundation crochet chain stitch. If a pattern requires 16 chain stitches, you will chain 20 stitches, and insert the crochet hook into the 5th chain stitch from the hook.
Step 2: Yarn over twice, and insert hook into the next stitch
You'll find this stitch is incredibly similar to the double crochet stitch—the only difference is how tall this stitch is. The taller the stitch, the more yarn overs we'll do before inserting our hook into the next stitch.
Step 2: Pull working yarn through the first loop
There are now four loops left on the crochet hook
Step 3: Yarn over, and pull working yarn through next two loops on crochet hook
There are now three loops on the crochet hook. Repeat step three twice more, until there is one loop left on the crochet hook. The Treble Crochet is complete!
From here, the remainder of these stitches are intuitive. Once you know how many chain stitches are needed for each stitch at the beginning of the row, and how many yarn overs are needed before inserting your hook into a chain stitch or crochet stitch below, you know how to work these stitches. Follow the rules and table below as a reference when working these stitches in a crochet pattern.
