I made this scarf 4-5 years ago and is one of the only scarves that I've made with wool-blend yarn.  I loved the color with the brown, pink, and green variegation and this yarn was incredibly soft.  Since it's been a long time I have to guess at the pattern, but I think this scarf is made entirely of double crochet stitches, stitched for the length of the scarf rather than the width.
