Another easy - peasy D.I.Y
I love old apple crates.
We have a few around the house.
My mom mentions often that there's no where to put her tea.
So I went to the local hardware store and bought four pretty industrial looking castors
(rolling things at bottom)
Then screwed them to the four corners.
Now we have a rolling side table for the livingroom.
The kids think its another one of their toys... they take it all over the first floor of the house.
