Aran / 47% wool, 30% acrylic & 23% alpaca. - I love working with this yarn. At first I was sceptical because of the acrylic content but it knits and blocks beautifully. It's not horribly expensive and comes in some really nice natural color ways. I knitted both a beret and scarf in this and both turned our very nicely.
By the way, I would love to read yarn reviews by the members here especially some of odd blends that are available these days. I'm alway looking for a new yarn experience. Also, as I try new fibers I'll post my thoughts on them.
