Unfortunately she has not given this stitch a name, so I will un-officially call it French Knotted Chain Stitch. Should any reader of this blog ever have seen this stitch and know its name, please let me know in the comments below.
Work it like this:
Stretch the fabric in a hoop.
Wind the thread twice around the needle to make a French Knot.
Insert the needle near where it came out, and then take the needle out a bit further down, like you would with a Chain Stitch.
Make the thread go from right to left under the needle.
Pull through and make another French Knot in the same way.
Make another combination French Knot and Chain Stitch
and another one.
