On Sunday, I finished casting on 449 sts for the outer edge of the Stora Dimun Faroese-style shawl from Cheryl Oberle's book, Folk Shawls http://www.cheryloberle.com/BooksPatterns.html
Which is why, in my first response to this thread, I inquired whether the OP's project is starting at the outer edge and working back to the "beginning," as this Faroese shawl does. I mean, the rows have got
to be smaller than 449 sts!!! Who could wear it otherwise?
