How to Crochet A Chain Stitch
The chain stitch crochet is the first and most basic crochet stitch. It does not make fabric on its own, but must be paired with another stitch.
Yarn over and pull the yarn through the loop already on the hook to form a new loop. Be careful not to tighten the previous loop.
Repeat to form the number of chains specified in the instructions. Do not count the slip knot as a stitch.
