Three needle bind off
This photo tutorial shows you how to work a three needle bind off to create a neat seam as shown on this pixie hat pattern
When working this method with an odd number of stitches, place the extra stitch on the front left hand needle and pick up 2 stitches from that needle, plus 1 from the back left hand needle in step 1 of this tutorial. Knit 3 stitches together in step 2. Follow exactly as shown for the rest of the stitches.
