The first quilt class I ever took, we did a sampler QAYG. What we did was choose a quilting template and incorporate that design in different ways in each block. Mine was a design that looked like 4 spades (like on a card), and in one block I'd put a spade in each corner, in another I used one spade in the center, etc. I'm not sure if I'm explaining that well, but it worked. That way, each block is not exactly the same, but it is coordinated.
