I am having a hard time finding one thats not crazy overpriced. I figured maybe i could get a plush toy, gut it and put some kind of spring in it, but im unsure what i may be missing or what kind of spring i would even want, it would need to be able to hold shape for puppetry but not be too stiff that it wants to shoot out of where its hidden. My initial thought was a metal slinky cut down, but would that be enough? maybe with a weight in the bottom to help force it down? Hoping someone might have some experience in making one. Also on a side note, whats the best way to put a false bottom into a hat so i can hide a prop.
