Despite the effort of the nupps to drive me insane, I have finished my Swallowtail and am delighted with it.
In fact, I might even consider doing it again, though this time I would be prepared for the nupps and how to "cheat."
There are more details about the finished shawl on my blog.
This Knitalong was a great help, not only in dealing with the nupps but also in selecting the yarn. Thanks to all of you!
