This sweater is basically a cardigan built onto a half pi shawl. So much easier than it looks! The lovely model in the blue version is a size 3-4, 5’8” and is wearing the small. The somewhat shorter larger lady in the rust version (me) is a size 12, 5’6” and wearing the large. The Shawl is knit first then stitches are picked up along the straight edge of the shawl for the cardigan. Any DK weight yarn can be used, cottons or silk blends would also be great.
