I much prefer machine quilting on wall hangings. I only have a few here that I have kept over the years and only one was partially hand quilted and it just felt out of place. Attic Windows is easy to stitch in the ditch for the window panes and stippling can be a good option to tightly quilt to fill in a space and leave unquilted whatever it is on the window pane. I can wait to see what you are doing...
