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 was a collage of coloring pictures. This would add some interesting designs to the background (top picture)
Then white and black paint was used to cover the coloring pages with an interesting patern (middle picture)
More collage was added using music paper and different tissue papers. Structures where made with glass beads modeling paste and some plastic butterlies. She decided she wanted 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.
