Here is a stitch from the Chain Stitch family. Detached Chain, or Lazy Daisy as it is also called, is often used for flower buds or together with other stitches to make decorative Crazy Quilt seams.
The stitch we are learning today is based on these individual Chain stitches, but when they are threaded, they make a nice and structured linear stitch.
The threading can be done with a variety of 'difficult' threads like metallic, chenille, knobbly or very fibrous types.
I found the instructions in Mary Thomas's Dictionary of Embroidery Stitches and in Reader's Digest Complete Book of Embroidery.
