This is the Country Style Cardigan by Sirdar. I knit it in Jaeger Extra Fine Merino DK and absolutely loved working with it. I'm really sad that it's been discontinued because it really is a lovely yarn.
This is the 3-4 year size. The ribbing was worked on a size 3 and the body on size 6. I wasn't crazy about the way the sleeves set and like usual with Mary Elizabeth's knits, I didn't have time to block. She seems to know how to take great care of hand knits so I'm hoping she'll press them as suggested to take care of that.
