To assist you in choosing fabrics for a OBW, type oneblockwonderdesignhelper into google. It's free. Open fabric on bolt, take a pic, go to design helper and import pic, change fabric width to 20" if pic is taken with fabric folded on bolt, and make and then make hexies. You get a preview of what your quilt will look like. Very helpful as some fabrics I thought would work great turned out to opbe only so-so. Happy Quilting!
