Yes you can tie. I tied one with embrodery floss, matching the floss to the fabric color. I tied in every hexagon. There is a photo in the gallery. You could hardly see the ties, sense they match the fabric. I have also done one using an embrodery stitch in each hex. It sort of resembled a star. I love hand quilting, but hands are getting to old and stiff for that, and I stink at machine quilting! You do what you have to do!! By the way. You have a beautiful GFG top!
