Ruffle scarf of ruffle yarn can be knitted in different ways. I like to knit on a rectangular loom. The loops keep good and you lose them not, that can happen on the sticks. Ruffle scarf is lush. I recommend this method for the sticking.
A ruffle scarf consists of a band ruffle yarn. You put up 6 stitches, and place the stitches every other time.
