How do I make an increase purlwise?

Help! Is there a video anyone can recommend for this?
Thanks!

I didn’t find a video, but what I do is lift the bar between the stitches from back to front with the left tip and then purl into the loop in the front.

Most of the ones listed on the Increases page are shown for doing it on a purl row too. Just look for the video icon under the description of the increase.
