Use Grimas Mastix Extra to attach the oblique pieces step by step. Apply glue to the part of the skin concerned and press the cut surface/obliquely cut side into the adhesive.
Attaching sequence: you attach piece 1 just under the chin, with the point forwards.
If necessary, piece 2 can be made smaller by pulling off a piece from the cut surface towards the hairs. You attach piece 2 to the chin, in the opposite direction to that of piece 1: the point points downwards in the direction of piece 1.
You attach pieces 3 and 4 close up on the left and right sides of pieces 1 and 2, the points pointing out in the same direction, namely forwards.
