Paragraph 123. Treble featherstitching, as the name suggests, consists of three stitches arranged in featherstitching. It is started in the same manner as the single featherstitching (Paragraph 121) a second stitch is added making it a double featherstitch (Paragraph 122), a third even parallel stitch is added which completes the treble featherstitch as shown in the upper portion of Figures 21 and 22.

Treble featherstitching is used very much the same as single or double featherstitching.
