Here is another ruffled scarf. This is not a very good picture, but then sparkly yarns never show up good. The colors are brighter too.
For this scarf I cast on 8 stitches, and it is 48 inches long. The white/gray one I cast on 10 stitches, and it turned out about 40 inches long... but it was a different brand of yarn. I am working on another one in blues, and I was going to have 8 stitches in it, but it turned out to have 9 stitches. I thing I am going to "knit two together" and go down to 8 stitches though, because I do like the length to be a little longer.
