What you need to get started

To get started practicing, pick up your needles and yarn.

In the tutorial, I will use size 9mm (US 13) needles and super bulky yarn – Lion Brand Wool-Ease Thick and Quick.

You can use any kind of yarn to practice, but choosing larger needles and super bulky yarn will make it easier for you.

Choosing a yarn where you can see the stitches will help you to see what is happening with your stitches.

    Insert your needle into the first knit stitch, as you would normally knit a stitch.
    Insert into the stitch with your right needle, wrap the yarn around the needle and place the needle to the front as if you are going to slide that stitch off.knitting into the front of a stitch

  2. Step 2 – Knitting into the second stitch

KFB Knitting Tips

Take a look at my tops tips for working this increase below;

  • Be careful how tightly you pull the yarn when you work.
  • You don’t want to pull so tight that it makes it difficult to get your needle in there to make the increase.
  • Follow the instructions in your pattern, to make sure you are making the increases in the right places.
  • Practice with a swatch before you take on a pattern that uses these stitches.
  • Watch my video tutorial to see how this KFB stitch can be worked easily before you start.

  1. The. Pattern indicates the squares re to be knitted separately. Does this mean each square is to be bin off and then sewn together? Thanks for your help.

    1. Hello Thelma,
      If your pattern doesn’t say if the squares should be continued in some way – then I would think that they should be cast off and joined later.
      In the making up section of your pattern, it may give further instruction on how to do this…
      I hope that helps!
