With a tapestry needle and yarn, come up through the first head stitch on the right or left end of your work.
You can work from right to left, or left to right.
Go around the running thread between the first 2 side stitches.
This step really starts your graft.
Go back down into the same head stitch you came out of and up through the next head stitch.
Go up through the stitch to the right if you’re traveling in that direction or to the left if you’re going that way.
Repeat the threading process.
The best version of this seam is made by grafting live stitches to the armhole edge, but you can use it with a bound-off edge, as well. Just go into the stitches (heads) directly below the bound-off edge.
