What is 3-needle bind-off?

This is a technique that lets you "knit together" two edges while binding them off. Instead of binding off each part separately and then sewing them together with a needle, you do both in one operation with an extra knitting needle.

Advantages of this method

  • Stability: Creates a firm seam that doesn't sag or stretch.
  • Time-saving: You avoid assembly with needle and thread.
  • Clean result: Gives a very straight and neat seam on the inside (or outside).
  • Secure: Since the stitches are knitted together, there is no chance of the seam "loosening".

How to do it (Step-by-step)

  1. Position the parts: Place the two parts to be joined (e.g., front and back) with right sides together. The stitches should be on their own needles, held parallel in the left hand.
  2. The third needle: Use a third needle in the right hand. Feel free to use a needle half a size larger to ensure the bind-off edge isn't too tight.
  3. Knit together the first stitch: Insert the right needle through the first stitch on both needles at the same time. Knit them together as if they were one stitch.
  4. Knit together the next stitch: Repeat for the next two stitches. You now have two stitches on the right needle.
  5. Bind off: Lift the first stitch on the right needle over the second stitch, just like a standard bind-off.
  6. Repeat: Continue knitting together two and two stitches and binding off until the needles are empty.

Tips for shoulders

If you want a decorative seam that is visible, you can do the technique with wrong sides together. Then the neat bind-off edge will lie on the right side of the garment, which is very modern today.
