One "earthy" thing I do is try to keep useful items out of landfills so I keep my eyes open around the neighborhood on garbage day. My kids have gotten used to stopping on the way to school while I jump out of the car and grab stuff off the curb. Generally they pretend not to know me when I am doing this.
Sometimes I use items just as they are, but more often than not they need a facelift. Here are some items that got quite a redo.
We actually have two of these big oak desks I found. One needed no work at all and is where I keep my computer for coloring, the other is this one in John's studio. All it needed was a new top so we used leftover linoleum from our kitchen floor. Bonus: linoleum is self healing so you can cut on it and it makes a great production table. Another note about linoleum - real linoleum - it is made from organic materials and does not outgas any petrochemicals. A lot of people think you can't get true linoleum anymore but you can. We got ours from Forbo - you should check them out.
These pieces needed almost no work.
This one is still in progress.
These are awaiting their "makeover"
