Rosette of Thorns is a variety of Buttonhole which creates a decorative line. It is named such as it creates a decorative pattern of crown shapes linked together.
This stitch can be worked in a line or as a gradual curve, with arms of the stitch fanning outwards or in a severe curve to form a circle.
As with buttonhole stitch the line is worked from left to right. This variety of button hole is simply made up of groups of five buttonhole stitches.
These are worked with the base of each stitch placed close together and the upright arms of the stitch fanning out. A long buttonhole stitch links each cluster of stitches.
The crown shapes of this stitch can be further decorated by the addition of sewing on a bead or an isolated knot stitch, such as a French knot, a Colonial knot, or combinations of detached chain at the tip of each upright stitch. It is a stitch useful in crazy quilting and patchwork. A large variety of embroidery threads can be used, but experiment with a fine thread as it shows off its delicacy.
There are many other stitches that are classified in this group. The stitches that I have listed here in the Buttonhole family are:
