I tend to be a tone-on-tone person, it just adds that little lift, especially when I an going to applique something on it. I also like that suggestion of decorating it yourself with tone-on-tone thread or contrasting. Even when I made a cloth doll, the tone-on-tone print kept the "body" from being bare and more of an underwear type characteristic. For the parasol girl block I am working on, it gives a little lacey look behind her.
