Because fabric stretches, you may end up with mismatched rows even if you use sewing pins at every seam. This can be frustrating for quilters, because it may mean ripping out stitches.
Step 1: Hold together the first two seams you’d like to join with your fingers, and carefully insert under the presser foot.
Step 2: Sew a few stitches back and forth just along the intersection.
Step 3: After backstitching, cut the thread and move along to the next intersection.
Once you’ve finished this step, open up the joined rows to see if any of the seams are amiss. If they are inaccurate, you can rip out just a few stitches and try again. For me, this added step can be a real time-saver! Once all the seams are aligned to your liking, finish stitching the raw edges together to join the rows.
