I've learned reading a bit more about historical quilts that my hand quilting is not what you might consider "fine". Usually I stitch right around 6 stitches per inch. I can't quite wrap my mind around how to get to 10 stitches per inch, but I've been working on my stitching a bit on a pillow cover I've got in progress. I've made it to about 7 stitches per inch, and I think I won't be able to get much finer with the wool batting. I'll give even finer a try with some cotton batting very soon.
