Changing the cover is easy. Simply go to the Layout and Design Center and select "Cookbook Covers". This will take you to a page that will allow you to select one of our professionally designed cookbook covers by clicking on the + sign to see the covers in each category. To select a cover click on the choose button. Then click "Save" to set that as your cover.
You can watch a tutorial video on this at https://youtu.be/wrDCN9sN3Ec
You can also create a custom cover by selecting that option on that page. Then you would use the photo manager to upload a photo and place it as the cover of your cookbook.
