First you need to build a hexagon on a piece of cardboard. To do this, you will need a circulation. In this example, the radius is 20 cm. So, forth the circle. Leaving the circus on the same width, put it on the circle line and make a label at the intersection area. Move the circulation needle to the point of crossing the circumference with the drawn, and make a label again. Repeat the action 6 times.
Using the ruler, connect the resulting labels. Cut the hexagon with the help of a stationery knife.
On the remaining cardboard, mark and cut the rectangles whose width will be equal to the desired depth of the shelves. For example, 14 cm.
Set on the rectangle the length of both sides of the hexagon. Excessive cut. In the center, spend something sharp to form a fold.
Similarly, cut and cut two more rectangles for the remaining four sides. With the help of the adhesive gun, glue the side parts to the hexagon and to each other. Additionally, it is accurately passing with glue on the joints. Remove excess.
For staining it is best to use water-emulsion paint. It does not smell, quickly dries and perfectly falls into the cardboard. Skin all surfaces. Do not forget about cuts.
If you want to give textures, go through the surface with a roller or an ordinary shopping sponge.
In conclusion, cover the shelf by quick lacquer.
Since the shelves are very light, then, provided that you will not load them strongly, there will be a bilateral tape type "3M" on the wall. Otherwise, fastening from will have to loops.
