Hi. I’ve done a couple building animated leering skeletons. It’s not terribly hard. I always use the low setting on my gun. Do only one finger at a time. The trick is to heat the entire finger thoroughly both front and back. You need to make sure it is good and pliable before you start bending it. Be careful not to overheat the fingers. You’ll need a pair of heavy gloves to help position them where you want them. You can use a damp rag to cool the fingers quickly to get them to set before moving onto the next one. takes a little bit of time, but I have had good results. I’ve bent their spines too using the same method.
