When inserting a foldover invitation into an envelope, the fold goes into the envelope first. Insert the basic components of the ensemble into the envelope (inner envelope for those items with two envelopes) in the following order from bottom to top:
Place the respond card face up on top of the respond envelope, which is face down, with its flap overlapping the respond card (see diagram 3).
Accessories are never inserted inside a foldover invitation.
Remaining pieces (directions, accommodations, within-the-ribbon, etc.) are usually layered on in ascending order of size from largest just above the respond set, to smallest on top. If your item comes with two envelopes, write the names of the guests, including children, on the front of the inner envelope using only the surname prefaced by Mr., Mrs., Dr., etc. Insert the inner envelope into the outer with the names facing the flap of the outer envelope.
