Painting with paper

I "paint" my images using tiny scraps of hand made papers. Sometimes I will use a vintage image, scan and size it then print it out on quality paper in gray scale ink. Then this image is cut out but not glued to the canvas yet. To color the image the hand made papers are torn in pieces, sometimes no bigger than a parsley flake so I can add shadows and depth. An example of this would be the shadow in the staircase in the first picture.
In the second picture the man and woman sitting at their desks are very small and detailed. The circus tent and sunset in the next two pictures are not as detailed, however there is texture. The easiest paper to work with is mulberry because it layers to blend colors but sometimes other papers will create interesting textures.
I use a gel medium to glue them in place, then trim the image before it is glued to the canvas.
