If you don't know someone else that would like the quilt, what about cutting it up (I know, I know, you spent all that time piecing it) and using it in a scrapy quilt.
It would be better to use the fabric for another quilt or two, than to just let it sit there on your shelf unfinished and unused. If the colors are not something you or any one you know would like, then you can always donate it to a charity, or send it off for the victims of Haiti.
