Quick pages and Quick Books describe "fixed" pages with windows for your photos. You can add text or more embellishments to them, but you can't change the components of the flattened page.
Layered templates are complete layered files to create scrapbook pages and hybrid projects. You can choose the papers and add/delete elements as well as adding text and extra embellishments. Many layered templates come with special frames, titles, or embellishments to decorate the page.
To use a template for more than one layout, you can add or remove pieces, flip or turn the template, resize parts, or use a part of one template on another page.
