Nice job. Its a beautiful sampler. What about some appropriately spaced straight line quilting. It would give a modern feel to the traditional quilt. Or if you prefer traditional quilting, you could do stitch-in-the-ditch with a cross hatch pattern in the open spaces. My personal feeling is a finished quilt is a great feeling of accomplishment. Perfect or not. I am sure you will get some great suggestions on quilting. Or may you can send it out to a long arm quilter to quilt? Either way I love your quilt top!
