That's the expression I was trying to think of earlier. It is kind of hard to translate. But wabi means something like harmony/balance and simplicity. Part of that is "less is more". Sabi is more complicated. IIRC, it connotes transience or sometimes imperfection. It is hard to explain but these two concepts are linked. So an Ikebana is sabi but so is an old teapot.
