I did my mask based on the movie purge .
Step 1: Started Off With a White Mask
1) Got a plastic mask
Step 2: Covered It
Started to cover it with plaster wrap
Continue the plaster wrap until it's thick enough ( about 5 layers )
Step 3: Putting Details on My Mask.
Then started to use acrylic paint and started to paint a lime green base. Added hot glue for the dripping blood , and stitches for mouth. Added red paint onto the dripping blood , and lighter lime green for mouth.
Step 4: The End of My Mask
I cutted out cardboard for the headband and also added wire for support underneath it , also cut 6 triangles that are 3 by 8 , I cut 1 inch tabs so they would fit on my headband and painted them lime green. I hot glued them to my headband and glued the headband to my mask.
