Black Glue Painting

I’ve been having fun experimenting with black glue painting on acetate. What I have learned so far is that black acrylic mixed with white glue (roughly 50/50) is fun to draw with, IF you put the mixture back in the glue bottle and you draw on acetate with the orange tip. Let it dry, and then fill in the bumpy areas with more paint mixed with glue. The mixture does stick to the acetate amazing well, and best viewed, I think, on a window.
