In this video, we learn how to do a purl increase stitch in knitting. First, make sure your yarn is in front, then do a normal purl stitch. Before you take your yarn off the left needle, go into the back of that stitch and pick it up from behind. Then, do a normal purl loop. After this, take the needle off. This is all you have to do to do a purl increase while you are stitching. If you don't understand it at first, then keep practicing and you will eventually learn how to do this. When you learn it, enjoy and continue knitting!
