I was also very interested to see how a BID head would look, but it turns out it's impossible to put a BID head on a KID body. The two dolls have oppositely engineered neck joints. Whereas the KID, and all larger dolls, have a rounded dome-shaped neck, and a concave hollow in the base of the head, BIDs are the opposite with a ball protruding from the bottom of the head, which fits onto the concave neck.
Now I have to design some KID patterns so I can make Lonnie something to wear while she goes away to be painted.
