I've really gone the rounds with this one. After running out of yarn and subsequently being unable to find a cone in a matching dye lot - I went with stripes in the stockinette section with the mismatched dye lot. I'm just glad it's done and I can move on to other projects!
Rock Island Shawl pattern with no modifications, knit on size 6 US needles using Southwest Trading Company Xie in color 479. This one took about 469 yards (51 grams). What really surprises me is that my first version only took 478 yards (52 grams) of the same yarn - I should have had enough leftover of the blue to finish this without running out. What a mystery!
