Try this format. I think it might give you all the pizazz you want and solve your sashing problems at the same time. It is a non-traditional style that apparently was designed by a 14 yr old GD of one of our members. It's very attractive. Anyway, it might help you to think outside the box, or outside the rectangle. Good Luck.
