@Maximilian I know someone who does a lot of dollmaking type stuff. Their needlework is Impressive, and beads and bones and other stuff often get involved too depending on what the little thing wants.
Here's one they made for me several years ago! The dolls scale up in complexity really drastically but this is the one that lives with me!
