It's hard to explain without a picture, I'm at work and can't post one.
not by rows, by "area". You will want to look at the quilt and have all the stitching blend so that you can't really tell what the "area's" are. Or row for that matter
If someone else can't help you with a picture, I will try and check tonight when I get home to see if I have a picture of what I am talking about.
Hopefully someone else can help too!
