Choose things that are timeless. You don’t have to spend a lot of money. There are folding chairs that cost $10 to $15 that are great design, just as there are chairs that cost thousands that are junk.
Our favorite cups are plain white Wedgwood ones designed long ago. Five hundred years from now, they will still be beautiful. And they didn’t mess it up with decoration. There was no need to.
You can reach timelessness if you look for the essence of things and not the appearance. The appearance is transitory — the appearance is fashion, the appearance is trendiness — but the essence is timeless.
