This is a fun item to knit. Only 3 sts arecast-on initially and the item is knit diagonally, sort of like a dishcloth!
I would suggest not using Mosaic. I had some beautiful Ella Rae super-fine heather that I had picked up at Tuesday Morning that I used instead. It’s much nicer for an item so near to theface - the Mosaic seemed to have a scratchy quality to it. I also knit this cowl with a strand of Noro king combined with the super-fine merino.
