When I have seams to align (in blocks and/or rows), I first pin them, and then I put about 5 stitches at each intersection (if your machine has a thread cutter, it makes it even faster to move from seam to seam). I then open up my block/row and check to make sure the seams are perfectly aligned. If they aren't, I only have the 5 stitches to remove (instead of an entire row of stitching), realign, pin, stitch again and recheck. If they are all aligned, I know I can sew the entire block/row and my seams will be perfectly matched.
