Chain stitch the desired length you want for your scarf (approximately 150 chains).

Continue to make lengths of chain with desired yarns, leaving about 5" at end for tassels.

Lay your chains next to each other and tie with decorative yarn, creating your scarf.

Another great look to this is braiding the chained pieces together. Of course you will need at least three chains, Or make three sets of chains and braid together for thicker scarf.

Use decorative yarn to wind around your chained pieces, or think about using a yarn needle and stitching them loosely together.
