Finding the Edge
Trimming the Mask
Trimming is a delicate matter. If you've become a paper mache zombie during the last few steps find your mask maker brain again and take this part seriously. The trim line for each mask is going to be different, based on a feeling of rightness.
Ideally, the mask will end where the planes of the mask meet the player's head. Generally, that's before the hairline, in front of the ear, just under the chin of the person wearing the mask.
The mask's edges will be convex. Never concave. Avoid two curves coming together into a corner or a hard edge.
Finishing the Paper Mache
Edging the Mask
Just glue is fine. Tiny strips. Keep it ragged.
Smoothing it All Out
Wood Filler
Can mix with a little glue to keep it flexible. Not too thick, too much sanding. A few coats. Three is awesome.
Paint and Color
Bringing life to the mask
Color, mixing, dry brush.
