With the various Slide Layouts in PowerPoint you can create good looking slides. For example, you can use the ready-made layouts available that contain pictures or charts or you could use a separate layout for the opening slide. While duplicating and editing Slide Layouts is a great way to make small changes, it’s not the same as creating a Slide Layout from scratch. As an analogy, duplicating and editing a Slide Layout is more like using a coloring book to fill color between the lines of pre-drawn art — but creating your Slide Layout from scratch is more like starting with a blank sheet of paper and drawing your art before you start coloring between the lines. You can decide which of these approaches works best for you.
