I know what you mean ... I bought a bunch of fabrics for my bedroom dresser runners... started it and now I can't stand to even look at them so I'm scrapping it and starting over..
If you don't like it for yourself and you don't mind making a quilt for someone else, use it. If you don't plan on giving someone a quilt in the next year or so, set it aside and use it for backing or for accent material for other projects. It might be just perfect for something else ;)
