This archival storage box helps you organize your incoming R.S.V.P. cards and store them for posterity. The box itself is ready-made. To augment it, first glue a simple calligraphed card to the outside, indicating what's within. Next make a checklist, either by hand or on a computer, including the invitees' names, plus spaces for you to fill in their replies and any comments. To attach this to the inside of the lid, make a special holder, as follows: Cut card stock to just smaller than lid. Cut ribbon to wrap across card stock as shown, and glue ribbon ends to back. Glue the card stock to underside of lid. Once the glue has dried, slip the checklist under the ribbon straps.
