Starting with 4.2 ounces, I did a traditional three ply and got a final skein that's somewhere in the range of 352 yards.
I'm really very happy with the results. Right off the bobbin, the skein looked mostly blue, but after its finishing bath, it skews much more green in person. I love the little specks of burnt orange and yellow that pop up from time to time.
One day, I'll knit this up, but for now, it's joining the other skeins of handspun. I think that small stash I have built up will be a real treat to break into when I have time to knit again.
