The Shawl from Hell

It sneaks up behind you in dark corners and dares you to finish it.  You see a cute shawl in the new issue of Knitty, but you can't cast on a new one until you cast off another.  With every pattern repeat the centerline becomes increasingly erratic and non-linear.  There is no way to fix it without ripping out the whole thing.  I have committed to only wearing this folded and wrapped and what not.  I showed it to several muggles who didn't notice the hideousness, but I know it's there.
