How to create a simple light box

I wanted to create a light-box but all I found on the internet was complicated structures. To do those you needed windows and elements that are not easy to find. In this  

Step 1: You will need:

- A box with its lid [I use the "KASSETT"box from IKEA (13x15x11 3/4") (33x38x30cm)]
- A3 tracing paper
- Small lamp (I use the "LAGRA" lamp from IKEA)
- Paper Cutter
- Pencil
- Super Glue
- Ruler
