The Bullion Knot
Here you can see bullion knots and french knots. The bullion knots are long sausage shaped knots and the french knots are little dots.
The French Knot
A row of pretty little knots…
The combination of the buttonhole stitch and the stem stitch around a motif, in this case with three different colors, allows the motif to raise up a bit and provides more texture and a 3-D effect. One of the things I do the most is to use several rows of stem stitch. I love the way it feels and the shading possibilities. I consider it my signature style.
