You’ve to be an artist since the first step is making a clay sculpture of the mask. When its dry and its surface is smoothed you have to pour a mixture of liquid plaster gypsum on the model to create the cast you’ll use to produce the masks.
You need a thick blotting paper, vinyl glue mixed with upholstery glue, water and a brush.
First of all pass Vaseline on the cast for the mask not to stick on it.
Wet the paper, place glue on it and proceed placing strips on the cast starting from the borders and going toward the center. Each strip has to be pressed into the cast and they must overlap. For details smaller parts of paper are required-
After you’ve done three layers of paper and glue the mask has to dry for one or two days.
Finally you cut the edges and the eyes with a scalpel.
Next step: the decoration…you have to be an artist again…
