Packing foam? The texture of this material is similar to the skin. I put pva glue to stiffen it but it didn’t work because it couldn’t absorb it. I will also paint it with acrylics to see the result. I am not sure yet, I have to do more tests. I don’t think that is the right material for my installation because is made from plastic and I want the material that I will use to be more natural because my artwork is a representation of a womb that is a body part. Something alive with flesh and blood and movement. Not plastic.
