Ohhhh, Thank you!! I have been pressing my seams open for years. Not because I was told to do it this way, of course. When folks at my guild would see me doing this, they would cringe and shake their heads. Didn't matter to me. My way of doing it worked for me. I have never had a problem with my seams not being strong enough to hold. Finally I have it in writing where it's not only okay, but made better by pressing open. Whaaa Whooo!!
