I'm starting to knit my first Baktus scarf. I'm using a standard Regia sock yarn skein and Size 2 needles. I guess I'm also taking a risk of sorts because I don't own a scale and am going to eyeball when to start reducing the dimensions of the scarf. For those who have already knitted this scarf with one skein of sock yarn, generally what measurements can I expect of the finished scarf?
