So many of the Knot By Gran’ma crochet patterns use this crochet technique. It’s called joining in, and today we’ll learn how to do it with a single crochet stitch. Why do I need to know how to join in? You’ll want to join in when switching yarn colors on a piece. If your crocheted monster doll has a blue head and now needs a green shirt, you would join in with the green yarn onto the already worked blue yarn. Sometimes you’ll be joining in to position your yarn a certain way that has to do with the structure of the crochet piece, or when you need to attach sections of crochet to each other. It’s really easy to master this quick little crochet method.
Start off by making a slip knot in yarn that you are joining in with. Place it on your crochet hook.
With the slip knot behind your hook, insert the hook into the stitch that you are joining in on. Yarn over and pull the loop back through the stitch. You’re now set up to finish a single crochet stitch with 2 loops on the hook.
Yarn over again, and pull the yarn through the 2 loops on the hook. You have just joined in with a single crochet stitch! Yaaaaaay! You can continue crocheting across your row or round… or do whatever the crochet pattern tells you to do next. It’s that easy.
