Thanks for the suggestions, Theresa! I actually have some of your 2 ply, but I want to wait to use it until after I have done one ribby wrap with yarn I buy at the local yarn store. I am a newbie knitter and I like to have somewhere I can go for IRL help if I get really stuck. They help you for free if you are using yarn you bought from them. The one from your list I know for sure they have is Lamb's Pride worsted. I love the results it produces. The one thing I don't like about it though is that the mohair makes the yarn a bit fuzzy and harder to make sene of when you are picking apart a mistake (to make matters worse I unwisely picked a dark color for my first soaker).
I might go ahead and use the Lamb's pride worsted though if that's the closest thing they have. They have a yarn called manos del uruguay that is a blend of a blend of Corriedale (?) and Merino. Anyone familiar with this stuff?
