For those taking Bob's class at QSDS who are having trouble visualizing what he is asking for, I will post some pictures of the fat quarter sandwich. You can make the sandwich white on one side and black on the other. Then take one sandwich in white and attach 3 inch strips of solid colors and on another sandwich use printed or textured. Then do the same in black. OK I know you are confused. Just look at the pictures and you will see what he wants.
