Size and use of your photo collage creater.

patsystoutmercer

I love your photo collage creator, however, I need 8 1/2" wide by 11" high size for my husband's personal history book he has been working on. Are there plans to provide the rectangle sheet I need instead of just the square one? Perhaps the "Aspect ratio" feature could help me, but I don't understand it. Could you help me with my concerns? And will new designs be coming out?
