I'm making an afghan with all wool. Sure, it's a bit tricker to wash, but I'm glad that it's wool. You could keep it and to clean it put it in the washer and fill it up (no agitation, of course) with Eucalan or some other wool cleaner, then spin and lay flat to dry.
OR, you can take it apart
and make other things out of it as rebecca and nicole suggest, since you don't like the pattern.
