Follow along to learn how to do a three needle bind off!
1 With the right side of the two pieces facing each other, and the needles parallel, insert a third needle knitwise into the first stitch of each needle. Wrap the yarn around the needle as if to knit.
2 Knit these two stitches together and slip them off the needles. Knit the next two stitches together in the same way as shown.
3 Slip the first stitch on the third needle over the second stitch and off the needle.
