Rather than buying business cards to share information, you can make your own notecards. To do this project, you need a piece of paper, and a pair of scissors. You can print the paper beforehand to customize your notes with contact information, pictures, or other ideas.
With this technique, you can make a notepad that does not need glue or any other fasteners. These notepads can be made in just a few minutes, and use common materials.
There are photos of this project.
