I used Marti Michell's templates which would make several sizes of blocks, but I did find them a little confusing at first. The Deb Tucker method of cutting a bit larger than needed and then cutting the pieces down to exact size would be useful for SaS. And if you don't mind paper piecing a whole quilt (which I loathe!), that would be the way to go. Pay close attention to how you press the seams, though, because you will want them to nest as you put them together.
