You did a fabulous job on this qilt. The "quilting" really does make it. I love machine quilting for the amount of quilting you can get onto a top. There was a good deal of blank space on your quilt and you filled it beautifully. 'Makes the blocks "pop".
I hand quilt but also machine quilt. Different quilts call for different methods.
I recently hand quilted an almost 100 year old top for a client. It was so poorly hand pieced that it just wouldn't have worked on a longarm. With hand stitching, I could pull and tug to get it right. My client (in her 70's) cried when she saw it because her grandmother had made it. The finished quilt (once ugly) had become beautiful.
