This is the Highlands Shawl from Cheryl Oberle's book, Folk Shawls.
I knit it on laceweight yarn instead of the "standard" worsted weight. Using a US size 3 needle it still ended up being a generous 90"x44" in size. The yarn is Alpaca with a Twist, Fino. It took approximately 745 yards. (My experience with her book is that the sizes she gives are much smaller than actual - I must be a VERY loose knitter - no comments please.)
