I also posted this on general knitting.
I'm making Barb's Koigu Ruffled scarf and not sure how to do the blocking. I don't want to flatten the ruffles out, but it's done in all stockinette so I know it's going to curl like crazy.
Wool? Gentle wash. Lay out, pinning the center to length but leaving the ruffles loose. Some people put stuff (cotton, socks, fabric) in the folds to ruffle them but I think if you just fluff with your fingers creating a nice back-and-forth along the length and let it dry it will be okay.
