From the pattern:

Just perfect for the breezy office or when you need your fingers free. And when you use Swizzle, you will need just one skein to make both these and the beanie.

Companion pattern to Ridged Beanie.

Pattern uses both US #5 (3.75 mm) 16” circular and double point needles.

Swizzle has been discontinued. A good substitution would be Paca Paints.
