I think the open mouth picture is funny, if you ever want to take a picture of them with their mouth partially closed you can put one of those big metal alligator clips inside the mouth to hold it closed more. I put my puppet's body over plastic drink bottle weighted with a little sand or water to hold them up when my sons don't feel like being my models.
Thanks Snail, Beleive it or not I had bought a bottle of rootbeer just for the bottle to make a puppet holder. LOL. I'm still not real pleased with Bertha's expression , going to have to work on it a bit more.
