This scarf was made with 1 skein of the Katia Tul. I used a size 13 needle (an 11 would probably do just fine as well), and cast on 7, and the scarf is about 41" long. You could always use 2 skeins for a much longer, fluffier scarf, but this one is plenty long and ruffly! The pattern for this yarn suggests a size 7 needle, but it's much too closely knit, and the ruffles don't have room to do their thing. We still have a good array of colors in the shop, so stop in and check it out!
