I had accumulated a large pile of fabrics I collected for collages and it was growing uncontrollably. I decided to organize them by value. That was too foreboding at first so I sorted them by color (hue) then I took each pile and took out the light ones for the box of light-values.
Next I pulled out the darkest value ones for the dark box. That made it easier to fill the medium box.
The fourth box was for larger pieces of cloth.
What fun. But I sure had a backache after all that working with piles on the floor.
