I agree with sewcrafty...if you are using a design wall or can lay it out on the table, try laying the whole block out on point so that the individual blocks are square to the table...or lay it out on a sheet and turn the sheet so you are looking at the corner of the layout (does that make more sense?) that should give you a better visual of how the piecing will go together. After you get the first one figured out, later diagonal rows will make sense.
