This is a really easy project and you may already have the materials lying around the house.
The table is lightweight, fairly study, and useful for putting things on.
And when you don't need it anymore, you can recycle it!
Things you need:
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.
