op, do you have a queen size bed in your house? if not, i'd exchange it for another king size IF IF IF you truly love it and want to use it forever. this is so me. I am very picky but when I love something, i want (and will!) use it forever, so yes, if I found a great deal on a GH quilt that I loved, i would buy 2.
but it doesn't make much sense to me, to keep a size that you don't have a bed in, unless you think you will be getting a queen guest bed?
