Materials Needed

Before we begin, gather the following materials:

  1. Rectangle paper (preferably thick and sturdy)
  2. Ruler
  3. Pencil
  4. Scissors
  5. Adhesive (glue or double-sided tape)

Folding the Paper

  1. Start with a rectangular piece of paper. The size of the paper will determine the size of your envelope.
  2. Place the paper horizontally in front of you.
  3. Fold the bottom edge of the paper up to meet the top edge, creating a vertical crease in the center.
  4. Unfold the paper and lay it flat again.

Creating the Flap

  1. Take the bottom edge of the paper and fold it upward, aligning it with the center crease created earlier.
  2. Make sure the bottom edge slightly overlaps the center crease, leaving a small gap.
  3. Crease the folded edge firmly.
  4. Next, fold the top edge of the paper downward, aligning it with the bottom edge. The top edge should slightly overlap the bottom edge.
  5. Crease the folded edge firmly.

Sealing the Envelope

  1. Apply adhesive (glue or double-sided tape) along the side edges of the bottom flap.
  2. Fold the bottom flap upward, pressing it firmly against the side edges to seal the envelope.
  3. Let the adhesive dry or set for a few moments.

Customizing Options

  1. You can personalize your envelope by adding decorative elements such as stickers, washi tape, or hand-drawn designs.
  2. Experiment with different paper colors or patterns to create unique and eye-catching envelopes.
  3. Consider using recycled materials to make eco-friendly envelopes.

Tips and Tricks

  1. Use a bone folder or the edge of a ruler to create sharp and crisp folds.
  2. If your paper is too thick to fold easily, score the fold lines with a ruler and a blunt edge before folding.
  3. Ensure the adhesive is applied evenly and sparingly to prevent it from seeping through the paper.
  4. If you want a more secure seal, you can use a small adhesive sticker or wax seal instead of glue or tape.
  5. Practice on scrap paper before making your final envelope to perfect your folding technique.


By following these simple steps, you can easily make your own envelope using a rectangle paper. It’s a creative and cost-effective way to add a personal touch to your mailings. Experiment with different sizes, colors, and designs to make your envelopes truly unique. So the next time you need an envelope, try making one yourself!
