Adding borders to a project is a common task in Photoshop. Often it can be done with relative ease; especially if the image is flat (meaning it contains one layer). Other times though, if the image has multiple layers that float and expand outside the boundaries it can be an altogether different story. Since both scenarios crop up from time to time I decided to write a solution to both, first the simple flattened image, then the more thought provoking layered file.
