i always start from the middle & work my way out on any quilting project, as i learned years ago from books. it is easier for me to remember where i am and what i need to stitch next. when i am quilting, i do ocassionally start down a path already traveled while doing sid, i stop ...find where i should be by looking at back of quilt re-start. after all done, i go over the back side snipping threads, removing unsatisfactory areas of stitching and duplicate stitch lines. i place pins on missed lines & areas i have removed stitching and need to re-do.
