Some quilters prefer hand quilting the top, batting and backing together, as opposed to machine quilting. Good hand stitches should be as consistent in size and small (more than 10 stitches to the inch); with consistency rating higher than size.
In the above photo, a one inch grid has been hand quilted. The stitch size is about 8 to every inch. (As you can see, my hand quilting is not so great!)
