What You Will Need:
A recipe for fauxtex prosthetics (tapioca flour, water, coconut oil, plain gelatin, skin colored makeup)
A straw cut in pieces
Step 1: Finger Molds With Playdough.
Mound it up so it's at least three inches high. Flatten the top. Sink your five fingers into the playdough to just beyond the first knuckle. Remove your fingers, oil them well, and put them back in the holes to coat the "mold" with oil. Remove your fingers.
Step 2: Fill Finger Form With Fauxtex
Let the fauxtex cool about ten minutes. Fill the finger forms while the fauxtex is still somewhat hot. Use a toothpick to work out any air pockets from the fauxtex.
Cut 1 to 2-inch sized pieces of a straw and insert them into the tops of the finger molds, pushing them just below the surface and covering with more fauxtex.
Wrap the entire playdough mold with plastic wrap and refrigerate a few hours (I left mine in the refrigerator overnight).
Step 3: Remove Fingers From Mold
The fingers will looks messy with playdough. Rinse the playdough off with cold water.
The fingers will have a little "skirt" at the top. Leave this edge on. It will help the finger stick to your window.
Step 4: Glue Fingers to Your Window
Coat the stub of each finger as well as the smudges on the glass with rubber cement. LET DRY AT LEAST 30 MINUTES.
Stick the fingers onto the glass.
