Decisions decisions

I'm trying to settle on a theme for our living room and the upholstery fabric for our chairs, ottoman, and sofas that we got for FREE! I've been in and out of the local fabrics stores several times and I'm just a little underwhelmed by the choices. I'm currently browsing the Finnish design fabric mecca called Marimekko and I'm loving their selection of upholstery fabrics. I've been to their flagship store in Helsinki Finland and it's absolutely wonderful. We bought a piece that was designed after a Russian church and made a wall-hanging from it.

Maybe you can help me make a decision. First, lets have a look at the chairs that I'm going to upholster. They are a Danish-like design.
Here's the idea - we already have some black and white paintings that we bought in Russia and we want to continue with the monochromatic color scheme and then add pops of color. So I'm gravitating toward black, white, gray and charcoal fabrics at the moment.
