Introduction: Cardboard Folder

Hello! My name is Thibo Castelein and as an assignment for school, we had to create something useful out of a cardboard box. There also had to be a logical link between the box and the innovated product. In this instructable I will show you how to make a folder out of an A4 paper box.

Step 1: What Do You Need?


- Cardboard box for A4 paper (obviously)

- Rubber band


- Ruler

- Set square

- Glue gun

- Cutter

Step 2: Make the Template

First unfold the cardboard box, next cut the cardboard at the right measurements. You can find the measurements in the technical drawing. Cut against a ruler to make sure the cuts are straight!

Step 3: Glue the Box Together

Fold the outer edges and then the lowest piece on top of the middle piece, so the outer edges allign with each other. Then glue the outer edges together using a glue gun.

Step 4: Insert the Rubber Band

To ensure that the folder stays closed, use a rubber band that will lock the top piece. Place the rubber band in the provided cutout. Make an overhand knot at each side to make sure that the rubber band will stay in place.

Step 5: Result

Now insert some documents and you're done! Your own handmade cardboard folder which you can take to school/to work/...
