I don't follow anybody's rules but my own....I press my seams open, match them up, pin both sides and don't remove the pins when I get to them...I just go really slow! I have bent a few pins and dulled a few needles but my seam ripper? where is that thing anyway....I can never find it! LOL
Seriously, I know this isn't the "correct" way to do this but I was also told there are NO rules!!! I make mine up as I go along...whatever works!
