Most of my scrap projects are random and controlled at the same time. I use a 6 row of 6 blocks per row designs (my own designs) and I usually use 8 differant prints of the same color. It is scrappy as in I don't like to use the same one twice but I also build a design by placing the colors where I want them. When I do a star for instance the points of the star will be 8 diff prints of blue or green etc and the backgrounds will be 8 diff light fabs.
