Yarn over

To yarn over means to wrap yarn over a crochet hook. It is the most basic step to every stitch in crochet.

You can use yarn overs before or after you insert the hook into the next stitch, and sometimes you yarn over two or more times, depending on the stitch.

How to yarn over

Wrap the yarn from back to front over the hook (or hold the yarn still and maneuver the hook).
