Paper templates for the two shapes that make the goggles. I found the shape of the two ovals [the mask] by laying cling film over my face. Ruth traced what she thought would be a nice shape directly on the plastic which was laid against my face. I then asked her to trace the actual perimeter of my eye. After that I just put the plastic on paper and cleaned up the shape a bit before cutting it out. I only found the shape of the oval mask like this. Read on to see how to find the eyepiece shape.
