Like almost everyone else, I usually press to the dark side and I've had to re-press a seam when I'm at an intersection and need it to go the other way. Don't worry Newbie, it will all become second nature before long. Also, not to confuse you but when you have 4 seams coming together, nip a stich out of each of them once they are sewn together and then 'fan' them out. It takes the bulk out of your seams.
