How to KFB Knitting Tutorial Knit Front Back
Learn the KFB knitting increase. To KFB you will knit in the front and back loop of the stitch.
Materials
- Any weight yarn. The kind of yarn I'm using is a #5 bulky weight yarn, pictured in Lion Brand Homespun Yarn (98% Acrylic, 2% Polyester, 6oz/170g, 185 yd/169m) color: hepplewhite.
Tools
- Matching needle size to your yarn. I'm using 8mm US Size 11 knitting needles with 24" cable.
- Yarn needle
- Measuring tape
- Scissors
Instructions
- We'll begin with a single stitch. You can cast on 1 by using a slip knot on your left needle. This is your first stitch. You will knit into it.
- Insert the right hand needle in the front leg of the stitch.
- Wrap the yarn over the right needle.
- Pull the yarn through the stitch.
- Without sliding the stitch off, insert the right needle into the back leg of the same stitch.
- Wrap the yarn over the right hand needle.
- Pull yarn through to knit the back of the stitch. You'll have two loops on your right needle and one loop on the left hand needle.
- Slide the stitches off the left hand needle. You will now have two stitches on your right hand needle.
- Turn your work so that the needle with the stitches on it is now in your left hand.
- Now you are ready to start the next row. Knit the front and back loop following steps 2-8 above for both stitches. The number of stitches will increase by two, so you will end with 4 stitches.
Turn your work.
- For the next row, we'll only KFB on the first stitch of the row and the last stitch. Since we're working in garter stitch we'll knit the middle stitches. To do so: Knit the front loop and the back loop of the first stitch, Knit the next two stitches and then knit the front loop and the back loop of the last stitch, turn your work. = 6 stitches
- You can continue the stitch pattern to keep increasing by 2 stitches: KFB, K across until there is one stitch left, KFB, turn your work.
