The feed dogs will pull the seam on the bottom butting it closer to the one on the top. It's not always possible to do this, but I try!
..this is it, along with pinning to anchor...but, make sure your pins are thin shafted or they will misalign that seam match. As you get more proficient, you won't need to pin those seam intersections, but at the start it helps...then your fingers will become very sensitive to those seams. Don't pull on your fabrics as they are being stitched by the machine, let the machine do the pulling.....and the most important......make sure your seams are consistently the same....carelessness in piecing can make joining those seams more difficult than it should be. Having said that...they will look perfect as you ride by three feet away on a galloping horse!
