My finished shawl weighed 368 grams, or just
under 13 ounces, so should take a total of 1365
yards or about 1248 meters of yarn to complete,
but you might still need four skeins of yarn, for
color options.
Color 1: Magnolia Leaf
Color 2: Glazed Pecan
Color 3: William Morris
Color 4: Nutmeg

Pattern includes notes about a smaller version, which could possibly be made with just 2 skeins of yarn. That has NOT been knit, however.
