So, once again, what are these posters talking about? Finger pressing?
You set seams with a hot iron just as they were sewn (iow, while the fabrics are still right sides together)
before pressing them open or to one side. It cannot be done by finger pressing. The first photo in the link given previously is setting the seam. See if this video explains it better for you.
