Found!
My 'good' scapular.

Under a book on my dresser. I have been puzzling for days how I could lose something that is worn under my clothing....not like an earring back, button or a left behind sweater. Oh, well. Don't know how it got there. I'm just happy to have it back, without having to have it surgically removed from one of the dog's intestines. (My fears are not unfounded - I've heard of dogs who have needed emergency surgery for eating pantyhose, Easter grass, Christmas tinsel and other non-digestible blockage producing stuff.)
