Go & search out the laundry room - I found several of Mom's things with her name label missing hanging in lost-and-found in that way. I also did a room search once - closet by closet with a nurse along with me, & turned up some of Mom's things in other resident's rooms. Unfortunately, we also suspect a few of her nicer things "grew legs & walked out the door", accompanied by a staff person.
I certainly hope it comes back where it belongs, or I'd be raising a fuss with the administrator of her former location. You put a lot of love & time into the quilt.
Hoping it returns,
Jan
