I have dozens of doll projects, a few of which are being worked with now. The nice blond paper mache head getting a new body is an American doll not found too often. Her facial paint is pristine, never mind the loss of a bit of shoulder plate.
I ordered a nice pair of old wax over papier mache arms for a doll needing them. They will do very well, To clean them I will use some Johnson's paste wax on a soft cloth. This is a good way to carefully clean soiled wax dolls, taking care not to remove any wax that is painted and must stay, dirty or not! Some wax and wax overs have eyebrows and lips painted under the wax and others are painted on top of it. Determine carefully which case you have before trying this. e
