For me, it's a mix. My first was just cuz she was so lovely. My second because I wanted a tiny, and she was so cute. My third, because she was a great deal, and oh, hey, I could justify getting her because I could use her for a character for a Middle Grades book cooking in my head. Then I needed her twin bro. Then my grail (still working out her character.) And finally, I just ordered a little dude because SALE. I mean, because I needed a beautiful little boy (and a hamster, apparently.) So overall, for me it's mostly been dolls first, characters later, but not always. Oh and my twins aren't cooperating very well, because they now look entirely different from my book characters. Not sure who's going to have to evolve there. Or maybe I just need 2 more dollies. . . No. Mustn't think that way.
