I have one skein at 270 yds, 5.4 oz (153 gr) and one at 330 yds, 6.1 oz (175 gr) so about 600 yds, 11.5 oz. I took a close-up to try to capture the rich color. Still didn't quite manage, but it's closer.
I also washed up a bag of Polwarth I got at the Jan 3 St Distaff Day spinning event I attended. This was in the silent auction, and my initial bid of $5.00 won it. Nobody else wanted it, apparently. (There was a lot of awesome stuff there, to be sure!)
It started out as just over 7 oz. I washed it, and it took two days to dry. I finally resorted to drying it in my oven (gas range with pilot light, the oven stays at a consistent 100 degrees or so). The finished wool weighs in at 4.91 oz (139.6 gr). It lost about 28% of its weight, in grease and dirt, after washing. I love the colors in this little batch of wool!
