I think the muslin background would work but I like the idea of using the cheddar color or maybe a light tan color. Pathways were traditionaly green so using a dark green in the CW fabrics would look great. The pathway can be diamond or hexagon shaped. There is a link to the QB Quilt Gallery in the QB, I think it's the 2nd or 3rd post. Look there at the GFG pictures. There are a few with the green pathway and you get to see several ways to arrange your GFG blocks. I think it will be beautiful when finished!
