Using sharp scissors, cut along the line carefully to cut the eye-patch out of the latex Quasimodo application.

LATEX PROSTHETICS = Latex prostetics
Take a Grimas Artificial Eye and apply Mastix Extra on the back to glue it into the application.
For a good adhesion you press the eye into the glued edge, remove it for a couple of seconds so that some oxygen can get in and then you stick the eye on firmly.
Pre-colour the eye patch with Camouflage Make-up in the same pale shade you will use next for the whole face.
