I was going to suggest you look at the pink and green one for the subtle contrast.
Are you planning white for the background? Perhaps lay your fabrics on the white, fanning each group out, to emulate the effect of the pattern. You might get a better sense of how it would look.
Subtle contrasts can be very effective. With the white background, I think the fabrics you have would find their own definition, and keep a nice soft look.
My only thought would be for you to check that the blues/purples definitely belong in each group. Looking at the photo there's a few that look like they might work in the other group. Of course, you have them IRL and we may not be seeing the true colour, once photo'd and then viewed on our monitors.
