The Trick To Send A Letter Without An Envelope.

by admin

No stamp or no envelope = no letter.

However, there is a trick that allows you to save envelopes.

Something not so new since it dates from the Great Russian Patriotic War. But it seems to have passed away.

Fortunately, we are here to bring it back to life.

The triangular letter

I, who communicate more by email than by mail, obviously no envelopes at home. But, during the holiday season, my grandmother demands letter-writing vows.

It was on the Internet that I found the solution, a half-century old solution: the triangular letter. It’s beautiful, isn’t it?

It is simply abouta folding, invented by the soldiers of the Second World War in search of family and envelopes.

The letter scribbled on any blank piece of paper made itself as an envelope thanks to an ingenious triangular folding.

How to do

Here is the folding below:

Before seeing the folding steps together, remember to write your letter on your A4 sheet first. It will save you from having to unfold it.

Here are the steps of folding the triangular letter, following the short instructions from left to right:

1. Lay your A4 sheet (already written) flat.

2. Take the top right corner of the sheet to fold it to the left to the edge.

3. Take the top left corner to fold it to the right to the edge.

4. Fold the bottom left and right edges of the sheet inward.

5. Finally, fold the sheet between the 3 triangles so that only one remains.

6. And There you go ! All that remains is to write the recipient’s address on the face of the large triangle. Here we go !

So that the letter remains well closed, I usually put a small piece of Scotch at the top of the triangular letter. That’s how I’m quiet.


1. Great savings

The triangular letter is the best way to save money on envelopes. 1 set of 100 ready-to-mail 20 g envelopes in Green Letter, costs 100 € !

2. Very convenient

Wherever I am, a simple pen, a piece of paper and a stamp are enough to create a single letter and original.

A good way to please loved ones when traveling.
