Stitch in the ditch is done when you Don't press your seams open. (There is no ditch when the seams are open.) Your blocks are lovely and it will make a wonderful quilt. I would spend the extra time to ditch stitch it, probably not every ditch but at least around each design element. I don't think you should have trouble stitching through the seams, but that really depends on the machine you're using. Maybe try it out on a test piece?
