I've spun up a sweater batch of Hello Yarn's club colorway, "Troll" on Polwarth. I had six bumps, or 24 ounces. I started with a "fauxlag" prep and spun a simple two-ply. It is just about 1500 yards.
I'm not sure yet exactly what this will be. It is enough for a sweater, obviously, but I haven't chosen the pattern. I'm thinking of alternating skeins. The color runs are pretty long, so I can probably get it to stripe.
