If you give charitable donations in guests' names, here's a beautiful way to let them know. Cut 7-by-4-inch pieces from patterned papers. Write or use your computer to print a message on the plain side of each sheet (if you're printing, do so before cutting the paper).
Measure and mark papers at 1-inch intervals; fold where marked. Cut top panel into a point. For each, adjust folds to make a hexagon, overlapping top flap, and seal with a monogrammed sticker.
