Welcome! Wrapping is a way to move your yarn when you're doing short rows in a way that will prevent holes. Just slip a stitch as if to purl, move your yarn over the needle to the other side, and replace that stitch. Usually at this point you turn your work and start working back in the other direction.
"Trust the pattern!"
