We do not have a lot of decoration stuff around the house. I like relatively empty and clean surfaces with a few nice items in neutral colors here and there. I have some bowls and stuff to put in bowls, such as pot-pourri, bits of wood, stones, sea shells etc. Every few months I do a reshuffle, buy some new candles and everything seems fresh again.
My favorite of this reshuffle is this jar that used to hold store-bought creme brulee. With some sand, a nice stone and two sea shells it reminds me of the beach and summer holidays.
