On NGS group, we're doing a study of Darlene Olivia McElroy & Sandra Duran Wilson's book "Surface Treatment workshop " This week we're looking at the section "skins". The authors state that skins are a sheet of paint or gel.
The basic technique is to pour and spread out a layer of acrylic paint, gel or fiber paste on to a clean glass, plastic wrap or polypropylene surface. And then let the medium dry completely, this may take more than a day, depending on the thickness of your medium. I decided to try three types of paint: Lumiere, Distress Crackle Paint and acrylic paint. The authors also mention that if your paint is thin you may need to add a layer of soft gel or clear leveling gel to provide added thickness so the paint won't tear when you lift it off the surface (I skipped this step).
