Welcome to your second crochet lesson - the Chain Stitch!
Did you learn how to do a slip knot? If you missed it, or forgot how, or need a reminder on how to pick the right size yarn and hook, take a look at the first Blue Corduroy Crochet Lesson on Slip Knots and Yarn Lables.
Crochet is a very addictive and relaxing skill once you get the hang of it. When my daughter Ginger first learned this chain stitch she was about six years old and she sat and crocheted a chain stitch that reached clear to the back yard! She wasn't worried about how fast she was working or what she was making, she was simply enjoying the yarn and the hook in her hands.
The chain stitch is a foundational stitch for most crochet projects and is also used in many crochet stitches. What you're learning here is proper tension of the yarn, using your fingers as guides, and how to twist the hook to guide the yarn.
Have fun getting to know your yarn and hook, and I can't wait to show you the next step!
