This ruffle yarn seems to be very "in" currently. I picked up some this summer from Finland. In fact, the brand I bought is a German yarn, which is pretty funny: travelling to Finland, buying German yarn and bringing it back to Germany :) But at that time, I had not seen that yarn here. Now it's everywhere!
So I made a scarf, too. I cast on 8 stitches, and knit until I had two balls used up. The result: a very ruffly, ca 180 cm long scarf.
Not sure I'll keep it though, I'm not sure where to wear it... I think I'll let it "marinate" over the winter (the scarf is very light and not very warm) in my closet and see what I feel about it in the spring.
Have you tried this fashion yarn already?
