Hang a curtain rod draped with sheer curtains (or fabric) at headboard height, behind the bed, then add some white holiday lights behind the fabric and across the rod, this adds a soft, relaxing, romantic feel to any bedroom.
First Apartment: Build a naked closet on a bare wall of your bedroom. Hang a curtain rod from the celing and attach a snazzy curtain to pull to cover and viola! new, bigger, and tailored closet to your needs. Ps this mean you now have an empty closet: convert to a cozy reading nook!
