I have seen some beautiful pressed flower pictures in stores that seem to have been put through some sort of lamination process. I purchased a framed picture many years ago and the flowers are still as fresh and vibrant as the day I purchased it. Is there a particular piece of equipment that is required for such a process. It can be done on paper, board, glass, almost any medium. I have been pressing flowers for years but don't have any way of truly preserving them. This seems to work. Any help would be very much appreciated. Annie
