If you want to play with blue and white decorating ideas for a bedroom there are some simple tricks to get the look, before you enter a long-term relationship.
You may have an all-white bedroom already that just needs a refresh and if not, create a backdrop with chalk-white paint for an easy base.
Then start adding small touches such as an accent chair in blue or a stack of books in shades of blue harvested from other rooms, or stems of blue hydrangeas, Iris, or cornflowers.
Try a blue and white water jug thrift store find, or a small blue and white pottery bowl for keeping rings and other trinkets.
You can take your time finding blue and white treasures and let them gradually take up more of the scheme, like a gently rolling, sea blue wave.
A calm, mindful way to decorate, and seemingly appropriate for the delightful scheme that is timeless blue and white.
