I reproduced a solid version using a paper model.
You can download the zipped file from HERE.
The site has a step by step sequences of well illustrated pictures on how to make it.
I'm not the author of the paper model. Credit to the author (I dunno who is he/she).
Once you have printed, and glued it, this becomes the base for your final mask.
Step 1: Materials.
- Clear tape
- White glue (PVA)
- Kitchen or toilet paper
- White flour (optional ) mixed with salt (you can find on the net different recipes for the mixture).
