What is with all of this ironing seams this way and that? i read the board every day.[/quote]
Others have answered the question as to why you press different ways but I want to emphasize that it is NOT ironing. Ironing is moving the iron back and forth while keeping the iron on the fabric. That can cause the fabric to stretch and your seams will not match up. Pressing, on the other hand, is placing the iron down on the fabric for a few seconds then lifting the iron up and off the fabric and then moving the iron to another place on the seam. Some people like dry irons and others like steam. It is your own preference.
