Purple Misty Alpaca in sports weight from Yarn Dogs. My first time to work with this yarn, it's like butta. It's chosen because of the color (picks up the purple in the variegated yarn), weight, sheen and price. The added ribbing will add another $17 to the sweater, which is reasonable for the handpainted merino wool. I can't believe how expensive it is to shop at regular yarn shops. $25 for a 50gm skein used to be luxury, now it seems to be the norm.
There are going to be five buttons. I'm thinking glass or something refined and eye catching.
