I've been sewing for many, many years and when I started quilting 10 years ago it seemed so strange to press seams to one side. And as for the statement that it made the seams stronger, I'd think back to all the garments and home accessories I had sewn and thought that very few of them came loose. The only word of advice I'd give is to make sure you shorten your stitch. I pressed seams open on a quilt I made about five years ago and then put it aside for quite a while before finishing it. When I finially got around to finishing it, I found the seams had come loose on the ends and almost every block had to be restitched at the ends.
