I have never been a fan of plastic wrap. It is just a pain to handle but now I may have to revise that attitude at least as to plastic wrap in the studio.
I am having fun getting some nice background colors with poured acrylic paints that then have plastic wrap lain over it for a few minutes. All the colors blend rather effortlessly.
I guess this is just one of the ways I am hard headed. I have just been trying too hard to get this to happen other ways.
