Do you ever think that such-and-such a doll would be perfect, IF....? That happens to me a lot. LOL So every now and again I stop and think about what the perfect doll (for me) would be.
I always come back to two options:
1) Diana Effner little darling doll on a body with as much poseability as a Fairyland Littlefee doll. It can have mechanical joints rather than ball-jointed ones if it's easier, and no changing out of eyes or anything, and be made of vinyl. The hands should be in a position that lets them hold props, too! It would be awesome!
2) A Littlefee with faceplates designed by Diana Effner. The set must of course come with multiple different expressions - neutral, happy, sad, angry, sleeping....all of them with faceups. This doll would fit in all the patterns I have for Littlefee, and be so much fun to photograph with the different expressions.
Which is not to say that I don't love the dolls I have, or am unhappy with them. Just that if one of those options ever became available, I'd start setting aside funds that same day. ;)
