I use a grace frame and start at the left hand top corner. I do a 6/7 inch stipple and then on the next row (right to left) I make sure I go up into the row above and fill in so you can't tell where the rows are. It fills it in nicely. The one thing you don't want is to be able to see definate rows of stipple. I think when you do stipple on a quilt on a machine that isn't on a frame you are suppose to start in the middle. Never could get the hang of that, too jerky.
