How to fill space between path and offset path?
I've cropped an image using the clipping mask tool and created an offset path around it. I want the offset to serve as a crop buffer for printing and cutting. I want the space between the original path and offset to show the cropped background image. A colleague sent me some files where he did this and I'm not sure how to replicate it. I've included two images for context. The first shows what I've done, the second shows what I want to do.
