With a few simple things you can make your own notepaper. Of course there are many ways to make your own stationery, but this is really very easy.

You only need:

1. Ecoline

2. Water

3. Brushes

4. Printing paper  

5. Empty bottles. 

As you can see in the first picture, you can make the color as intense as you want. 

Dilute the Ecoline with water to make the color as light as you think is beautiful or useful. When it's too dark, you will need a white pencil to write, otherwise you won't be able to read the letter.

Here you see how subtle it is. 

But it's just more fun than simple fine lines or white paper.
