It is a written pattern, available in both Swedish and English (US) with step-by-step pictures.

You can easily customize the size of the shawl by the number of repetitions of the pattern.

I have used Scheepjes Whirl, 767 and Whirlette, 866, for the last repetitions of the pattern and for the fringes.

You can make the shawl in any yarn you like, as long as you choose a hook adapted to the yarn, but keep in mind that the amount of yarn you need will vary.
