I wondered if you were quilting on a frame or with a hoop-I can't seem to manage quilting on a frame which is another reason I don't hand quilt many anymore. Too much moving around of the hoop and too much on my lap.
One of the things you mentioned earlier-it is always suggested that when you start quilting after you have not quilted for a bit-have a practice piece ready to get your stitches going before you start on the real thing.
Great job.
