The single crochet (sc) is one of the 6 basic crochet stitches. It’s a beginner-friendly stitch that’s easy to learn and fun to crochet. In fact, since single crochet is so common, it’s often the first technique a crochet newbie learns! Single crochet is so versatile, too. You can work single crochet in rows, joined rounds or spiral rounds, and in different parts of the stitch for ribbing stitches. Plus, you can use it to make edges, borders, and seams.
In brief, here’s how to work a single crochet:
Insert hook in next stitch (st) or chain (ch).
Yarn over (yo) hook.
Pull hook through.
Yarn over (yo) again.
Pull yarn through both loops (lps).
You are now ready to move onto the next stitch (st).
