1 Black marker pen
1 Piece of felt (in the absence of fake leatherette to simulate the skin)
1 Pair of scissors
1 Violet braided absorbable vicryl suture (alternatively, a needle and thread will do)
Step 1. Using a marker pen, draw the outline of your home-made nipple on the felt. If your rendition resembles a squashed club with a circle in the middle, you're doing well. This is what Mr A calls an aeroplane flap.
