First create a new layer. I called mine border. Click ok.
Then select polygonal lasso. (right click on lasso tool)
Create a border around the pic with the ploygonal lasso. Then right click inside the selection and choose stroke
Set the size you want (I used 2 px but the setting when I opened it up was 3 px)
Obviously I don't want a green border. So double-click inside the color box and choose your color (I used white0
Click ok and then the border appears. Next is to right click inside the box and click deselect. Then polish up the edges if needed with the erasor
That's it! It's a great border to use every once in a while. Hope this helps!
