To check for Balance? Can you either print out a photo of your design (black and white Laser is fine) or go into your computer file where your photo is, and click the button to FLIP your design. The idea is to look at your design 'backwards' or Mirror-Image. You can simply hold a hand mirror up to your design wall for this purpose. When the mirror image looks BALANCED, then your design will be balanced from the front side, too.
