Do you have a big piece of paper and want to make it into an envelope? You can do this easily with just a few folds. This is a great way to make your own envelopes for invitations, cards, or letters. All you need is a rectangle of paper and a bit of tape or glue.

What you will need

  • One rectangle piece of paper
  • A pencil
  • A ruler
  • Scissors

Step 1: Fold the paper in half

Place the rectangle paper horizontally in front of you. Fold the top edge of the paper down to meet the bottom edge. Unfold the paper, and then fold it in half again, this time folding it vertically.

Step 2: Cut the paper

Use a ruler and a pencil to draw a line from each corner of the paper to the center, making sure the lines are parallel. With scissors, cut along the lines. You should now have four equal triangle-shaped pieces of paper.

Step 3: Fold the paper again

Fold the paper in half again, making sure the creases are nice and sharp. Then, open it up and fold the top and bottom edges in to meet in the middle at the previous crease. Once again, make sure the creases are sharp.

Step 4: Cut the paper again

After the long side is folded, cut the paper vertically in half. It should be about 6 inches (15 cm) wide when it is unfolded.

Step 5: Fold the paper one last time

For this final fold, you’ll want to make a sharp crease near the edge of the paper. Unfold the paper, then refold it so the crease you just made is at the center. This will give you a nice, clean fold for the final paper envelope.

Step 6: Finish the envelope

To finish the envelope, simply fold the flap over and seal it with a sticker, a piece of tape, or a dollop of glue. And that’s it! You’ve made your very own envelope with rectangle paper.
