As a rule, once something is gifted, it's gone and out of my control. But I gotta say, if one of my grandchildren or children mistreated something I'd made for them, you better believe I'd be having something to say about it. I might say it lightly, but it would be said. To the 17 yr old, I'd probably say something like, "Dang, girl, if you don't want that quilt, give it back to me and I'll clean it up and pass it on to someone who needs it and will use it. No sense letting it lay there and rot." Then I'd hug her and say that next time I'll try to give her something more to her liking.
