Ribbon or Tape Yarn is a kind of novelty yarn. It is made of ribbon, but
generally not the kind of ribbon used in sewing and millinery. Rather,
they are ribbons made especially for knitting or crocheting, with some
in a tubular form, some woven flat, and some similar in appearance to
bias tape. Ribbon yarns can be composed of many materials, from
synthetics to silk to plant fibers.
