Details, details, details! It is the small details that make a dress stunning. Pleats were extensively used on skirts, hems, necklines to display the seamstress' ability. There were a number of tools used to pleat or flute fabric, some were flat like the one demonstrated here and others were cranked or required a form to use with a fluting iron. All in all, it required work that you didn't want to be continuously repeating when you wore the dress. This video demonstrates a pleating tool available today that is similar to the antique tool to the left that will make pleating much easier in creating your historical garment. She also recommends using a solution of water withe a tablespoon or two of vinegar to set the pleats. I have also used this solution to remove stubbon creases.
