I would stitch in the ditch. If you want decorative stitching you can then go behind your stitch in the ditch with the decorative stitching. When you finish your stitch in the ditch you may feel the quilt speaks for itself and needs nothing further. Now, please tell me why I didn't do it that way myself on mine!!!!!!!!!!! I am still ripping stitches. I didn't follow the rule and quilt from the center up, center out, center down, etc. I have a wave that runs through the quilt. I pinned and used decorative stitching on the full wave. I was off 1/2"!!!!!!! That's all. So I am ripping the decorative stitching out to work the 1/2" fabric ripple out. Middle out, middle up, middle down, etc. Won't happen to me again!
