Step by Step 3 into 9 TBL Tutorial


In this tutorial I'll be showing you how to knit the 3 into 9 TBL (through the back loop) knitting stitch. This is a stitch that apears in Estonian Lace knitting patterns as well as just Lace Knitting patterns in general & is a way of adding 6 stitches by increasing from 3 to 9 stitches quickly while adding a decorative element to the project. It can be a bit tricky to understand what is going on when just reading through written instructions for this technique so I wanted to do a photo tutorial to try and show how simple this technique really is.

There are multiple variations on this technique that can include anything from 1 into 3 (also seen written as "k1, yo, k1 into the same st") to 5 into 15 and beyond. It's a fun way to play with increases & shaping in a pattern & is worth taking a stab at if you're curious. The important thing to note if you're playing around with it is that you need to end with an odd number of sts because you need to "trap" the final yarn-over with a knit stitch.

If you're curious about the pattern that this stitch is featured in, I'm going to keep you in suspense for a little while longer. It's part of a soon-to-be-released lace shawl pattern that I'm designing & will be available by the end of January.

Happy knitting!

  • A project or swatch with stitches still live on the needles

  • Knitting needles appropriate for your yarn

Step 1:

Work in-pattern to the 3 stitchess to be worked.

Step 2:

Insert right needle through the back loops of all 3 stitches.

Step 3:

Knit 1 stitch through all 3 stitches. Do not drop the 3 stitches from the left needle.

Step 4:

Yarn over. Again, do not drop the 3 stitches from the left needle.

Step 5:

Insert the right needle through the back loops of all 3 stitches & knit them together. Again, do not drop the 3 stitches from the left needle.

Step 6:

Continue alternating yarn-overs with knitting 3 together through the back loop until you have 9 stitches worked into the original 3.

Step 7:

Once you've made the 9 stitches, you can drop the original 3 stitches from the left needle.


Follow pattern instructions for the following row. In this example, each stitch in Row 2 was purled to create a smooth fabric.
