I just completed a sweater (from Garn Studio) using the Muskat yarn. The price was great, but the problem was that it split constantly, and I was using Turbo needles. Have you tried the Safran yet?

I'm still waiting for my shipment to come in. I hope to be getting in a few days. I hope not to run into the same problem because when the yarn holds up well it makes the project so much quicker and more attractive. Which sweater did you make and how easy are the patterns to follow? I've copies several of the patterns for future projects.
