This is a very light shawl, for a heavier shawl, I would recommend using a heavier yarn and adjusting needle size to yarn.
One size fits most
Can be adjusted to for different sizes of yarn by adjusting needle size.
I used one ball Woollike Simili-Laine superfine in each color Navy and Mauve. Havier yarn weights will most likely call for more yardage. I did use ALL of the 2 balls of yarn I had.
