Ravelry: inglynch's Linook shawl - Good pattern for Yowza - BUT you need 220 yards of 4 colors. This would be a great way to use up leftovers you might have. But could be re-envisioned in other yarn weights.
Alternating garter and stockinette stitch in worsted weight yarn make an elegant blanket, bordered with a cabled knot edging. Meditative to make with a challenging twist, the Stornaway Throw is sure to become an heirloom for your home.
