What’s a skin? It’s a separate piece of acrylic without any backing or support. Any acrylic product when applied to a non-stick surface and left to dry, can be peeled off producing a piece of acrylic with no backing. This piece of acrylic, or “skin” can be used as a collage item in a painting, or as an entire layer of a painting.
What non-stick surfaces will work? Plastic garbage bags, plastic painting drop cloths at home improvement stores that are whitish and cloudy, plexi sheets called HDPE (High Density Polyethylene), Freezer Paper (found in grocery stores – not to be confused with wax paper) and protective plastic binder sheets found in office supply stores.
Which type of acrylic works best? The quick answer is that any acrylic product will make a skin. But to delve a bit deeper, let’s start by thinking of acrylic in two broad categories. There’s paint and binder. Acrylic paint has color, while binders come in 3 basic types: mediums, gels and pastes. So any paint, medium, gel or paste can create a skin, which means a skin can come in any color, opacity/transparency, thickness, sheen, texture or combination.
Some painting ideas with skins:
Make a variety of skins and store them for later use by stacking them together with freezer paper in between so they don’t stick together.
Cut the skins into specific shapes with scissors and glue them onto an acrylic painting using a gel as glue.
Roll them into shapes to add a three-dimensional relief onto the painting surface.
Create large sheets of clear skins, paint something different on each one, then arrange one on top of the other to create different effects (pictured below)

Create large sheets of translucent skins by using matte gels, or thin layers of paste, and adhere over a painting to create the illusion of depth. Optionally you can continue to paint over this skin, or add another skin layer.
