Despite the fact that I am trying to streamline my stash in anticipation of my (hopefully) upcoming move once I graduate... I came across this yarn at The Loopy Ewe. I adore the colors. I'm not sure I need a worsted weight merino yarn for socks but Thuja or the Cabled Footies from the One Skein book come to mind...
I haven't used the Boomerang before but I have used Fiesta Watermark and loved it (one of the best yarns I've knit with to date)
I don't need it. But I absolutely want it.
