My Stepdaughter wanted to make a large canvas for a wall in her living room. Something with only grey and white colors.
To make it more interesting the first step is a collage of coloring pictures. This will add some interesting designs to the background (top picture)
Then white and black paint is used to cover the coloring pages with an interesting patern (middle picture)
More collage is added using music paper and different tissue papers. Structures are made with glass beads modeling paste and some plastic butterlies. She decided she wants color after all so we made music notes from old colored wall paper and added them to the score lines (bottom picture)
She was very happy with the final result.
