… and absolutely straight edges on others. Why is that?
Is it cheaper to make the uneven ones, because I have seen some books where the price was the same as the straight-edged ones?
Is it traditional with some book binders and they bind them all this way? (I admit I haven’t checked this out, hence the question regarding tradition).
As a personal preference, it’s easier for me to turn the pages of the straight-edged ones.
