I'm a little late to the party, but am completely in love with Jay McCarroll's fabric, designed for Free Spirit. You can see the entire Center City collection here: Free Spirit Fabric. The photo above is the "Center City" line in the "Downtown" colorway and reminds me of a photo I took of a bit of rusty, paint peeling bit of the NYC subway (below).
Victoria Findlay Wolfe created an incredible quilt from Jay McCarroll fabrics that won best in show at QuiltCon 2013, photo here: Best in Show Quilt. My very favorite Swoon Quilt was also made with Jay's fabrics, take a peek: I'm a Ginger Monkey. Jay brings a much needed bit of edge to the quilting world.
