Miniature envelopes are easy to make at home using materials you probably have on hand. While they are too small to mail through the United States Postal Service without paying extra for handling fees, they are the perfect size for attaching a personal note to a present or a bouquet of flowers. A standard blank business card is a great size for a mini envelope enclosure note.
Cut the paper into a 5 1/2 inch square.
Place a business card in the centre of the paper.
Fold the paper up to the edge of the business card.
Fold the top of the paper down to just above the top of the business card.
Fold the remaining edges of paper in so they are just at the edge of the card.
Unfold the paper and set the business card aside.
Hold the paper so that the widest sections run horizontally down the middle of the tri-fold. Cut the 1-inch tall rectangular shapes off the two bottom corners. Flip the paper upside down and cut the rectangles off the last two corners.
Fold the two smaller side flaps in toward the centre. Apply glue to the lower two-thirds of these flaps. Fold the bottom flap up and press the edges where it is meeting the glued flaps.
Enclose a note. Run a glue stick along the edge of the top flap, and fold over to seal.
Any type of lightweight paper can be used for a mini envelope. Try recycling a magazine or newspaper page that might be of interest to the recipient of your note. Before applying glue in the last step, use decorative scissors to add interest to the edge.
