The table is lightweight, fairly study, and useful for putting things on.
And when you don't need it anymore, you can recycle it!
1 box, the right size to be the top of the table. I'm using a flat box that I think was originally part of the packaging for a laptop computer.
4 mailing tubes. The length of the tubes will be the height of the table. (The diameter doesn't matter too much.)
Some sticky-backed plastic, and/or anything else you want to decorate your table with. Plastic is good because it will prevent the table top from disintegrating if you spill a drink on it. You may like to put clear plastic over a collage or a painted picture, in which case you will need materials for that.
You will also need glue, tape, a pen or pencil, and a utility knife.
