This scarf is a knock off of the Emporio Armani Multi-thread scarf from the S/S '10 collection.
It is made with 3/4 inch wide (lengthwise) strips of knit fabric. The fabric naturally rolls into little tubes and doesn't fray. These are rough instructions for how I did it.
I cut 2 sets of strips, one 27" long and the other 38" long. It would save a lot of work if you cut one set of 65" strips.
I overlapped the ends of the strips and stitched them together by machine.
Next I gathered the strips together where at the seams. I took another strip of fabric and wrapping it around the strips, stitched it down by hand.
I tucked the ends in (see above) securing it invisibly.
For the other end, I wrapped with black knit fabric. It's a fun, unusual scarf/necklace and surprisingly easy to wear.
