Finally, I used up one cone of gray mystery yarn. This is how much I had left. Not even enough to get across the row. It stretched unbelievably far. You can see how skinny the yarn is. Lots of swatches, four 6+ foot scarves, one ring in a circle scarf and two hats. The hats and scarves are for charity.
OOps! Almost forgot to update my yards knit. Let's see. 1 yard x 604 rows = 604 for the scarf. 1 yard x 136 rows x 2 hats = 272 yards. Together: 876 yards. Not bad.
