Summary

This is a pair of "Neck Bolts" for a Frankenstein('s Monster) costume.

Instructions

Print in a silver or grey color, or paint the "bolt portion" to look realistic, if desired. I advise against painting the disc portion at all, especially the bottom, because it will be in contact with your skin.

Use Spirit gum to adhere the "disc" side of each bolt to clean, dry skin.
Use "fake skin", "Liquid Latex", and/or any other sfx makeup technique to hide the disc.

Use makeup to make the fake skin appear to be real.
