I have a lot of layouts with offset framing. For some reason, it appeals to me.
To do offset framing, make sure your outline is on its own layer.
Control/Command click on the thumbnail in your layers panel to get a selection Open a new layer above the photo and Edit> Stoke/Outline your selection on this new layer - choosing color and width from the screen that pops up when you choose this option.
Now this outline can be moved anywhere on your project, plus you can change/delete it any time - without affecting your photo.
Outlining on your photo layer permanently changes the photo - there's no going back
