From pattern: “This quaint little design is easy to embroider on the felted surface of this scarf because the felting creates a nice dense area that keeps the embroidery stitching from sliding between any knitted stitches.”

Pattern also calls for the following:
1 ball size 10 crochet cotton
tapestry needle
embroidery needle
single-strand embroidery thread (they suggest Natural Impressions embroidery thread by Caron) in the following colors:
1 skein light sage green (#5002)
1 skein dark sage green (#5000)
1 skein light teal green (#7024)
1 skein dark teal green (#7022)
1 skein light coral (#2075)
1 skein dark Indian red (#178)
1 skein golden yellow (#4003)
