So, a couple of years ago, I was in a puppet ministry at my former church, and of course, with there being people who had never even touched a puppet in their lives, the instructors (two nice old ladies), had to teach the newcomers the basics of puppetry. The first thing they started on was puppet mouth movements, or lip syncing. I don't know if they got this wrong or not, but they said that you were to NEVER move the top part of your hand, JUST the thumb, not even the tiniest bit. Now, with me being the puppetry nerd in the group, I raised my hand politely and basically said that I thought you were supposed to move the top just a little bit, to add some flexibility to the performance. Because the way they were doing it, the top of the mouth was so unflexible, the puppets looked like they were robots, and it didn't give off a believable performance at all. So my question is, should you move the top of the mouth just a little bit or keep it completely still? Sorry if this doesn't make any sense and mods feel free to delete this if it doesn't.
