From Vogue Knitting, Holiday 2003:
Lisa Buccellato romanticizes the cable by working classic rope and braid designs into a long and luxurious fringed affair. Knit the scarf to any length in gorgeous “Indiecita Alpaca Worsted Weight” from Plymouth Yarn Co.

From the pattern:
Long aran scarf with knotted fringe. Use 2 strands of yarn held together throughout.

Pattern Notes 20 st x 16 row aran braid chart.
