This large right-triangular shawl drapes wonderfully thanks to plentiful ribbing and the silk in Cascade Yarns Roslyn. Bold stripes sweep diagonally in a steady mathematical progression.

The model uses three skeins of Roslyn in color 10, “Cyan.” It took about half of the third skein of yarn. Cascade’s Llamerino or Aegean Tweed would be excellent alternatives to Roslyn. They’d give the same tweedy look, but required yardages would be different.
