My mistake

I been knitting the Mistaken Shawl by Dollybird Workshop. Out of some Noro that was given to me.   It is a nice pattern, but as I near the end I am convinced it is not the best use of the yarn.   

 So I am going to frog it and start over.    I fear if I finish it will just sit on the shelf. The yarn is to nice for it to languish unloved.
