The arms may pose the biggest challenge of reworking this doll, although I've developed a secondary problem. The doll is drying out and as it does, she's managed a crack under her chin that runs the length of her neck. I've kept on top of repairing it but I've discovered that less handling is better. Below is a photo of the first layer of putty applied to the arms, I'm in the process of a second coat. I'm hoping that's all she'll need.
