I have a greeting card that folds open left to right like a book. It also has an insert that folds open in the same way, but the insert is only attached on the left side of the card. So am I supposed to write directly on the insert, or on the right side of the card that is visible once the insert is folded back? There is not a lot of room on the insert and I have a lot to say. And why won't Hallmark make a card that is blank?
