I would choose 6 over 7, but not use both, as they are so similar. 1 seems a little heavy close-up, but it's effective from a distance. I think it's refreshing to have a light fabric in the mix, and I prefer 3 over 5. If going with four fabrics, I'd use 2, 3, 4 and 6. But I think the first six would be very nice, as well.
