I absolutely fell in love with this duvet cover.  When we received it, we realized it was just a "cover" and we needed to get a duvet to go into it.  No problem, right?  Wrong.  It is 104" x 88"; a true King duvet is 108" x 94".  It doesn't flow over the sides of my King mattress.  We have worked all kinds of things to try to make this work--new sheets to disguise it's lacking.  I sewed batting into it to create my own duvet.  I'm a seamstress, so now, it might become a dress.  Husband wants to just sew it to the duvet.
