I love simplicity, but it means different things to different people (see post here).
Claire, over at Just A Little Less expresses my own view well when she says 'Simplicity can feel like a luxury'.
The luxury of space, of a clear head, of time to think, to talk and laugh with friends and look at the view.
In another sense I love the luxury of good quality materials and craftmanship - I'd rather have one good item than lots of inferior ones. I think respect for good materials and honest makers is a good principle to go by as the consumers we all inevitably are.
I take my time choosing, then keep things for as long as they last on the whole.
I like mostly classical designs which don't date.
Do you agree that simplicity can feel like a luxury?
