WARNING!!!!

Please read if you want to do casting like this. Casting Plaster of
Paris in large volume can heat up to 140 degrees F (60 C). Easily fatal
in a horrible way. Use thin layers or plaster treated bandages so that
the heat can escape.

A test fit may have been a good idea, but she didn't appear ready for
full body immobilizer. I understand it to be euphoric to holy terror,
with nothing but your thoughts, heart beat, labored breathing, and a
tube in your mouth that your life depends.

I think this looks like a project he wished he had not started,,,
