I used several ways to colored the shed skin, there are dry color powder, acrylic colors and nail polish colors.
I mixed the dry colors with liquid rubber, and attached to the shed skin, make sure the liquid is completely attached to the shed skin. when they were dry, the shed skin were flexible again to some degree and touches like skin. According to the experiment, this could be a way to reborn the skin and color them.
I tried to attach these shed skin on the metals surface, and apply this way onto the jewellery pieces.
