I spent a few entertaining days making face masks to understand the process for a project, which consisted of a motion graphics how-to video.
Not only was personalized plaster mask making pleasantly mucky fun, it was also very informative.
I was able to cover a number of family members faces in plaster and sit back amused as they attempted to talk or scratch their nose.
Unfortunately none of my masks came out to a high standard but it was amusing nonetheless.
I highly recommend creating face masks. You can view my 'Making a mask' motion graphics video in my portfolio for all the info you'll need.
