Decorations: Wreaths are always a festive choice, and many fall wreaths will last until spring. Branches, and fake fruits such as apples or baby gourds are always a nice touch to any fall decorations. For an added sparkle, experiment with different spray paints or just add a glitter spray as a finishing touch. You will feel like it is fall in New England in no time.
The trick with a double bed is to simplify the entire look of the room (no clutter) and go with a more "reserved" look for the room. Keep the room as clean as possible; otherwise it may look as if the bed is lost at sea with your belongings! Another trick to give your double bed more of a profound appearance in the room is to invest in a good quality headboard. You may also want to consider finding a headboard with rounded edges to further compliment the simplified look.
