I have made several OBW quilts and sewn them on my DM. My favorite way of quilting them is to swing out from the seam and then back in - sort of like a cathedral window. I do this to all the seams and as they join in the intersections they form a six point flower. So I just swerve a soft zig zag to the points all the way to the end of a row and then swerve all the way back up the row. I hope I described what I do in a way that is easy to understand.
