First is to Select All... then ise the stroke command. Use the stroke to the Inside of the selection.
Second is to resize the canvas with the background color being the color of the frame. Just add twice as many pixels as you want the frame to be wide to the canvas.
Thanks fotomann forever. what a great tip. I tried it and it works great. Sure saves alot of time by trying to draw lines. And thanks to ddgg for asking the question.
