Paper-folded box

Use any rectangle or square. Try covers of magazines. The thicker the paper is, the stronger your box will be, but the harder it will be to fold; so try to maintain a good balance. Make sure all the folds are strong and well-formed.






Fold the paper in half, extend it back out and then fold each half inwards again to end up in the middle line.

Turn paper sideways and do the same exact thing as in step 1. But this time after the second fold, fold back out again and straighten the paper.

Fold the four corners inwards but do not exceed the lines that appeared after the second fold on step 2. Make sure not to fold in more than a third of the width.

Fold the edges on the middle line out over the triangles made in step 3 in a straight line.

Pull out slowly both sides over the middle line strengthening the edges and corners as you proceed.

Make two and fit them together. In order to do this, leave a little more space in the middle when you do the first fold in step 1.

Congratulations! Your paper box is at your service.
Have fun!
