The Helen Allen Textule Collection on the University of Wisconsin - Madison campus has several wreaths of human hair flowers + some ornaments. They are all made of hair of dead people as a memorium, each flower is tagged with the deceased's name by the original owner (maker?). I believe the Wisconsin State Historical Society in Madison, also has some hair wreaths and ornaments. I don;t have the telephone numbers off hand but the area code is 608 if you want to call for directory assistance.
