Used to indicate paper that is folded either at the top or along the left side. On a traditional, side-fold invitation, the wording is printed on the outside cover with the inside right and left panels entirely blank. If decoration is on the cover, the wording is printed on the inside right panel of a side-fold paper and the bottom panel of a top-fold. One item, â€œUnder the Chuppahâ€ is tri-fold with a fold on the right and left sides allowing three panels of printing when fully opened. Another, â€œL'Amourâ€, is folded twice from the bottom, then opens from below to reveal vertical printing along the entire inside.
