How to yarn over in crochet
A yarn over (abbreviated YO) in crochet is a fundamental technique where the working yarn is wrapped over the crochet hook from back to front, allowing the hook to catch the yarn and pull it through loops to create stitches.
Step 1
Position the hook in front of the yarn.
Step 2
Bring the yarn from behind the hook to the front of the hook, wrapping the yarn around the hook.
