I used the pages from an old book. You can use also pages from a magazine, but not a newspaper because they are thin. Fold your pages to form stripes.
Start gluing them together to form a base for the table.My base is 20cm in diameter, it was enough for the tray i used. When you get to the size it fits your tray hot glue it to the back of it.
I made 20 triangles for each row. Measure the perimeter of the paper base and divide it by 10. Make your stripes a little bigger, because you should calculate the joinings of the triangles.Mine are 4.9cm at each side.
Carefully start gluing, with white glue, covering all the sides of the paper to stiffen it a bit. Don't make it too tall, it will not be very steady. I made ten rows. Careful to make them straight! That's the tricky part! I think it is better to make a couple of rows, let them dry and then continue with the next one.
I covered the whole base with another coat of white glue, filled some blanks on the triangles also. Let it dry overnight and spray paint with the color you like!
