In brief - I love this yarn.
53% wool, 47% acrylic
Recommended gauge is 10 st = 3" with a #11 needle. I've been knitting hats and mittens with it on size 6 dpns. It makes a nice dense fabric, but not too stiff. I haven't tried washing it, so who knows? Maybe it poofs way out once washed.
Handwash in cool water or dry clean.
I keep finding good things about it. Sorry I keep comparing it to Noro Kureyon. I love Noro, and this yarn looks a lot like it on the shelf.
1. It's not very expensive - about $6 (US) per ball.
2. It stripes like Noro Kureyon - the color changes may be slightly shorter than Noro, but it has the same gradual blend effect.
3. It is not (very) itchy.
4. NO GRASS.
5. Easy to hand-wind. For Knitters Without Winders, this is a great feature. The yarn comes as a loose ball, which is fine, but I was looking for the color repeat, so I have wound 4 balls of this by hand recently. It has not tangled. Not once. Awesome.
6. It is spun more consistently than Noro Kureyon - same springy single-strand worsted spin (someone correct me if I am not using the term worsted correctly in relation to how yarn is spun).
Anything I don't like?
1. It doesn't break because of the acrylic content. Slightly inconvenient, but I can live with it.
2. Either the color pattern doesn't repeat, or the repeat is over 300 yards long, because I wasn't able to find the repeat after hand-winding three balls of yarn. (I was trying to match the Mumma Smittens.)
Bottom line: Would I buy this again?
I would. Especially if I see it on sale! One ball is enough for a pair of kid mittens, two makes adult mittens.
