After scoring your background or mat... use ink to detail it and pop it off the paper.
Here is a close up of boxed scoring on background and inked and a special marking on the square accent pieces that I scored and inked too.
This is my double page layout above using scoring and inking.. I love the effect with this technique.
On my sample card I scored the shape of bricks to form my background. As long as your consistent with your shapes and sizes they should look fabulous. Have fun scoring on your projects.
