I used 1/4" Thick walnut. There are instructions in the pattern on how to assemble. The one thing I want you to watch for are the sides. The angle causes the bottom not to be flat. You could cut the sides to the angle on your table saw. I find it easier to just let the sides over hang while gluing and flatten them at the end on my disk sander. The instruction show this process and an alternative.
