The mystery is revealed.... as Asma said they are doll parts. I am rolling oodles of heads for the dolls in my nativity set. I need 9 heads for each nativity so that is a lot of rolling since I sell them on my etsy store at Christmas. They are not on my site right now but I am getting some ready to list soon. This year I am making them all off white so they will be different than in these pictures but if I have time I will make these as well.
