Hi - I am looking to make a photo guest book. I want to make sure that the pages lay flat and that the paper is not going to smudge when guests write in it with a regular pen. I also prefer not to do the common 8x11 size that most companies offer. I'd rather a perfect square, or a vertical book (not a horizontal layout). There are so many photo book companies out there....which is my best bet without breaking the bank?
