Handmade mini envelopes are a nice touch for scrapbooking and mini cards. Write a mini note or cut out simple shapes, such as a heart, to insert in the envelope. Use pretty paper, recycled from gift-wrapping; unusual paper, such as grocery bags; or plain paper you embellish with cutouts or drawings.
Unfold a square-shaped used regular or mini envelope (from junk mail or a card). Use a knife to separate the glued flaps at the bottom. This sample will help you envision how the paper will be cut and where folds should be made for your mini envelope. Whatever size mini you make, the pattern for this simple envelope is the same: A square in the middle with four triangle-shaped flaps sticking out on the four sides.
Measure out and cut a 3-inch square (or whatever size you want) from your chosen paper. Turn the square so the points are at the top, bottom and sides.
Fold the two side points evenly into the middle of the rectangle so the points touch. Crease the sides for a clean finish.
Fold up and crease the bottom triangle to about 1/8-inch above the middle of the rectangle. You have created a little overlap of the bottom with the sides. Glue the envelope under these overlaps. Cut off or fold in the point of the bottom triangle that may not be in line with the side points. Fold down the last triangle to make the top flap of the envelope.
Use craft scissors to cut out the paper square with a decorative edge for instant embellishment. Other sources of recycled paper include greeting cards, calendars with pictures, wallpaper samples and pages from discarded books. When you are happy with the size and shape of your mini envelope, make a template out of cardboard or card stock. Then you can trace around it to make more envelopes instead of having to measure.
