Most of my scrappy are of the controlled variety. I tend to pick from a set number of colors and stick to that. I sort my scraps by color so it's easy for me to do it that way. The other way I scrappy is by theme. IE: Panda quilt, horse quilt, florals. So that still falls into the controlled area. I have never done a full out scrappy where you just grab and sew, although I will do that within my controlled choices.
