Remove heavy drapes and replace them with sheer materials such as voile or lace. You can find affordable materials at local fabric stores or use old pieces of fabric found at flea markets. Simply pin up fabrics with some tacks or sew a rod pocket at either end.
Also, check flea markets for summer-inspired paintings of flowers, cottages and beach scenes. You can also fill bowls and vases of inexpensive sea glass and seashells to bring a piece of the beach inside.
