My dear friend and kindred spirit, Joyce, coined this word.
Frankensteining: verb; to create a doll from elements of several other doll patterns.
Which is what I've been doing lately, and like the good doctor for which this verb is cognated (probably also not a word), I am well pleased with my final version.
This doll is a combination of the freely available Eva doll (available on Ravelry), the purchased Jane doll (available on Etsy), and my own Simply Ami doll, (available here on this blog), plus a bit of body tweaking.
The point is, if you have been making dolls for a while, you probably have a nice collection of patterns, and certain attributes of each doll that you particularly like. Don't be shy about combining the bits you like to make a doll uniquely your own. But keep in mind that this is not pattern design, and that credit to the original designers should be given.
So thank you, Jessica Doering, for the Eva doll that provided the size; Kelly DeSandro for the Jane doll that provided the shoulders, head, and dainty feet; Simply Amis, for the swing legs, and my own tinkering for the body shape and wig.
