For me this could go under resin casting or modeling. Vacuforming I guess is more modeling so I guess I will put in that category. This is my first attempt and as with any first attempt you solve the problem with the tools you have in your toolbox. That said, my way is definitely not the only way or even the best way but it's a start using what I know. I will use two tools from my tool box and they are Milliput epoxy putty and resin casting to create the vacuform bucks for the vacuforming process.
