I had a similar experience but not with a quilting hoop. My daughter gave me a cook book for Christmas.....shortly after Christmas I moved from the midwest to Ga; when I finally got my apartment and things sorted I got to looking for THAT cook book.....looked everywhere, went through everything.....called relatives whom I had been staying with until apt ready, nope, they hadn't seen it.
I thought I too had lost my mind. Finally confessed to daughter that I had lost the Christmas cookbook, which I named......her reply was, Mom, I didn't give you that book I gave you thus and so......oh.....the book that she had given me was sitting in my cookbook "rack" opened to a page that I had been using........In my mind I was absolutely sure she had given me another book..........
