Update: We now have a skein converter. It will show you how many balls you need per type of yarn and project.
To make a scarf, it depends on what stitch you are using and how long you want your scarf to be. We recommend between 1 and 3 balls of bulky wool.
One ball if you want to make a short cowl like the Downtown Snood.
Two balls if you want to make a scarf like our High Line Loop.
