Making a cut
To create an 'open wound', the Derma Wax construction has to be 'cut open' with the sharp side of a Derma Wax spatula. Lubricate the tip of the spatula with a little bit of Cleansing Cream. This will allow the spatula to slide more easily through the Derma Wax, preventing it from sticking to the spatula.
DERMA WAX = Derma Wax
DERMA WAX SPATULA = Derma Wax Spatula
CLEANSING CREAM / SKINCARE CREAM = Cleansing Cream
FINISHING

Opening the wound edges up allows you to create a tattered effect. Raise the 'wound edges' using a Derma Wax spatula, lightly lubricated with Cleansing Cream. Do this carefully.
Colouring: To add a suggestion of depth to the 'wound', colour the bottom of the wound using black make-up.

Then you colour the inner side of the wound with dark red make-up (Grimas Water Make-up Pure or Crème Make-up Pure).
Finally, you add Grimas Blood, Film Blood or Blood Paste, depending on the desired effect.

Blood
You can apply it directly from the tube or with a brush. Use a Grimas Stoppel Sponge or a tissue to disperse the blood around the 'wound', if desired.
