I think you should definitely keep it. When DH is thoughtful enough and cares enough to give you a beautiful gift like that, he really needs to know that you care enough about him to keep it. So what if it doesn't match anything else, who cares, there are a lot of things that don't match but are beautiful just the same,it is thought and love that went into getting that beautiful panel. That's like pics. and things that my children made when they were small, they didn't match but I definitely kept them and displayed them. I still have most of them, many are put away now, grown children, but I still cherish them. Glad you are feeling better and so was DH to get you something hoping it would make your day. Please don't hurt his feelings by giving it up to someone else. If you don't keep it, he may not get anything again.
