I am working on the same sort of scarf for my first project. Only mine is in lilac. I am no where near done (gotten just a little over 8 inches out of 5' done so far). You've got me beat!! Then again, I knit at a snail's pace, doing a row here and a row there, then putting it down, only to pick it up later and do another few rows.
