Lifted increases are one of my personal favorites as they are just so versatile. Interestingly enough, they are not very popular. As a result, you will find this increase under quite a lot of different names:

  • PRL – Purl right loop
  • PRLI – purled right lifted increase
  • RLPI – right lifted purl increase

I prefer to call it PRL but they all mean the exact same thing. It forms quite the neat and barely visible increase line on the right side – just one of the many reasons I am so in love with lifted increases. The corresponding left-leaning lifted increase would be LLPI.

Instructions: How to knit the right lifted purl increase

This right-leaning increase is knitted into the loop of a stitch one row below. Even though it is a stitch for the wrong side, most patterns will use it to create a certain effect on the right side.

Active Time 1 minute
Total Time 1 minute


  1. Insert your right knitting needle into the right loop of the stitch one row below the next stitch on your left knitting needle coming from below.

  2. Lift that loop back on the left needle.

  3. Bring the yarn to the front and insert your right knitting needle through the back of that extra loop.

  4. Wrap the yarn around the needle counter-clockwise.

  5. Pull the yarn through and drop the lifted loop.

Essentially you are working a purl through back loop into the lifted loop. Try to work close to the tips of your knitting needle so you don't stretch out the resulting increase too much.

How to use this purl increase for the wrong side

One of the most important questions with any knitting increase is its slant. If you look closely at the swatch above, I think the answer is quite clear. It’s definitely left-slanting and forms a barely visible increase line. In fact, I’d say it is the most invisible purl increase of them all.

On the right side, things are less clear. I do believe that both sides are quite pretty and usable. There’s no denying, however, that the right side is the most invisible and that’s the reason why this increase is typically labeled as right-leaning. I think it’s a bit confusing but for the sake of conformity, I’ll stick to defining the slant by the appearance on the right side.

At the end of this little tutorial, I quickly want to address the difference between PRL and the right-leaning lifted increase for the right side – KLL. And if you look at the swatch above, there is literally no difference other than the color. These two increases are absolutely interchangeable.

So, depending on the circumstances and your individual knitting preferences, you may use either version.

Anyway, that’s how to knit the right lifted purl increase. Comment below in case you still have any questions.

  1. Hi Norman, thanks for this great article. I have a question, in the section “How to use this Purl Increase for the Wrong Side”, the swatch photo shows that there were increases done on both sides, and the caption says both sides were increased using the PRL. On the WS, the increases on the right of the swatch seem more visible. If one wanted to do an increase showing on the WS, right of the swatch that was less visible, would PRL still be your best choice of increase?
