Oh dear, I'm a decorate anything in sight with the seasons person, and I enjoy it.
Like Whitewavemark2 my garden consists currently of dozens of lavender bushes, blue and white agapanthus, blue delphiniums, salvias and a group of sunflower tucked in a few corners. On the fences are shells, driftwood, bees, and a sign saying "to the beach". Indoors, most of my main rooms are white and blue, so the theme continues with the cushions, and jute mats on the floors, summer kitchenware etc. Then there's me, summer dresses, hats, various raffia bags, mainly blue and white, plus a bit of pink.
All the stuff will go in the loft come Autumn when I'll start all over again in orange and beige!
