You can also use posterboard. I found it works better because you can wrap it around your arm but it also holds together well as your template so you dont need to tape your arm and cut it out of cardboard
Mk only issue with this vid is pricing. activator creams for bondo and fiberglass resin =$10 all together. goggles= $4. respirator=$20. gloves=$3. and sculpting tools $5 for just a couple. So all together it ended up costing me around $100
I don't have anything against you or transgenders whatsoever but to me you didnt answer any of your own questions. You touched on portions of the scientific and psychologic aspects of it but not in depth enough. I'd love to see another video like this with a little more research behind it. :)
