I don't know if it's the most efficient, but here's the way I would do it.
Construct your black top. Divide the vertical space into four even parts for your columns. The tread itself is made from just one motif. It is flipped horizontally and vertically to create the different patterns. Play with the size until you find something that looks right for the scale of your top. I would make a cardstock template of it so I could just trace along the top and part of the bottom. Use a ruler to keep them in a straight line and evenly spaced. Here's a primitive Photoshop highlighting the parts in purple in case you need it. Hope this helps!
