Purl in front and in back?

I am having a difficult time. How do you purl in front and in the back of one stitch? Is there a video for this??? I am messing up my project and I don’t want to just give up on it…I’ve come so far lol!
:wall:

Thanks!

You purl in the front normally and then leave the stitch on the needle and come UP from the back of the stitch and wrap the yarn and pull it through.

Here’s a few links.
