A print client today submitted a file with a pinstripe around the digital image. One of the easiest ways to create this in Adobe Photoshop CC is to create a selection of the image’s edges and to stroke it.
You have three options on how the stroke would be applied. You can choose 1) Inside, 2) Center or 3) Outside.
What you choose affects how the corners of the stroked edges will look like.
(Just in case someone was wondering how to change the look of the corners )
