After I did my first and only bargello so far I realized I needed to make my focus fabric be at the bottom to make the undulations stand out more. Now our pattern was just a simple V shape so I think a lot depends on how many undulations you plan on using. Also I think that the top photo has 3 fabrics on the right side that appear to be the same value. If so you won't see a color change. Hope this helps a bit. I know I played with my fabric for about a week before making the final decision.
