For now, Grandma's dolly is going to sit around in her underwear. Once that would have been indecent, but nowadays, it just means she telecommutes. The silk dress dress didn't dissolve or shrink from washing, as I had feared, but it was so badly stained that I won't be putting it back on her.
I wonder what my mom would have made of e-commerce. It only took me half an hour to learn that this is what collectors call a "flathead" china doll, most likely made in the waning days of "lady dolls" (as opposed to "baby dolls") as the little girl's gift of choice. Although this doll is in relatively good condition and has most of her original clothes, she is just one of the common dollies. Collectors pay the big bucks for rare dolls that were never played with.
Meanwhile, after washing and ironing her complicated lingerie, I'm feeling fond of her and thinking about making her some new outfits. I believe I can make an acceptable period dress--perhaps a wrapper with an apron, or a shirtwaist and skirt. I do have those seven plastic tubs of fabric scraps, and fitting doll clothes is much simpler than fitting human clothes. Dolls don't need wearing ease and don't ever complain.
