This shawl takes its name from Snow White's stepmother, whose distinctive curving hood is the best example I can find of the shawl's finished shape.
The shawl uses a stitch pattern that is almost more air than fabric, making the most of Cabrito's fluffy texture. The mohair fills the spaces made by dropping triple yarnovers; the finished product is marvelously light yet warm.
It's not a simple knit -- there are yarnovers and decreases on every row, and mohair's fluff can also make it difficult to see your stitches -- but it's only a 6-row repeat, and your attention will be well rewarded by the finished product.
