K1tog Left loop and K1Tog Right loop

A step by step tutorial on the K1tog LL and K1tog RL decreases

I love experimenting with my knitting and trying to figure out new ways to solve old problems. One of mine has always been finding a decrease that leads to a similar effect like a KLL or KRL. And, lo and behold, with the K1tog LL I found a little workaround.

Now, I want to make this crystal clear that I made these two “decreases” up myself. I couldn’t find them in any knitting book but have no clue if I was the first one to ever think of them. So, I make no claim here. I just want to show you these techniques and why and how I use them.

Instructions

I’ll show you the K1tog LL first and then the K1tog RL.

Step 1: Slip the stitch you want to knit together.

Step 2: Pick up the left loop of the stitch one row below the one you just slipped.

Step 3: Slip the stitch you previously slipped back to the left needle.

Step 4: Knit these two stitches together though the back loop (here’s my k2tog tbl tutorial in case you need to catch up).

This will result in a very condensed line in your knitting. It really looks a bit like a more condensed SSK or so.

You’ll knit the K1tog RL as follows:

This version is a bit easier to knit because you don’t need to slip around so much.

Step 1: Pick up the right loop of the stitch one row below the next stitch on your left needle and slip it to the left needle.

Step 2: Knit the two stitches (or rather one stitch and one loop) together just like a regular k2tog.

The result will be a rather loose column of knit stitches, where, unlike when you slip a stitch, the float is incorporated into the stitch.

Use cases for these two decreases

First of all, I call them decreases because they are knit in a similar way but they are not decreasing your stitch count. They only bring a different structure to the fabric.

#1 Creating the perfect slopped neckline without a gap

Most people who knit sweaters bottom-up will bind off around the neckline and then pick stitches up. While this will reinforce the collar, it often will look less neat than a top-down raglan sweater kind of neck or the yokes so popular in Fair Isle knitting.

But here’s another method: You can slip stitches to cable/stitch holder. But there is a problem: Typically you would try to create a nice slope by slipping the first stitch after the stitches you slipped to the cable. But if you knit across, this will still leave little gaps.

If you K1tog LL after the gap (or k1tog right loop before the gap on the right side), this won’t create an eyelet and a tight neckline.

#2 Cinching the fabric

Another problem you might be facing has to do with the way KLL and KRL “cinch” the fabric because they steal a bit of yarn from the row below. If you were to knit a shawl with these increases, this would turn into a problem.

But this “issue” can also be used for shaping toys and other knitwear. But if you want to cinch something round symmetrical at the top and the bottom, you are facing a problem: There is no corresponding decrease that really steals yarn from the row below. You can slip stitches, but that also posses a problem.

Take a look at this swatch. I slipped stitches in the middle to shorten the fabric in that position. But because you are essentially creating floats, it creates an elevated sort of line that sometimes is not what you want.

Here’s a picture of the bottom of my pumpkin pattern. I did a K1tog RL/LL and you can clearly see how this helps to bring the segments of the pumpkin a bit too the front (or rather the create the indentation).

Other than that, I am not really using these stitches for anything else. The use cases are somewhat limited and it’s certainly not the first thing a beginner needs to learn. But, I guess it’s kind of interesting to know, right?

That’s all I can tell you about k1tog LL and k1tog RL. Feel free to ask your questions below!

  4. Thank you so much for this step by step tutorial. I was a bit confused with this step knitting the pumpkin pattern considering that it was not changing the stitch count. It all makes sense to me now. I do love how this added so much naturally knit shape to the pumpkin doing it with your stitches. Thank you again for the pattern and the detailed step by steps with explanations as well.
