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.--- maybe just a string of lights over the headboard :)
FALL/WINTER Starry String Lights - Amber Lights on Copper Wire Really like these lights in high visibility areas. They are battery powered. Consider for use in the table decor, place-card and wedding cake table, etc.
For my guest rooms ideas.only want Frech Vintage Cottage style in guest room and my office (-Mari Marxuach Parrilla)/ Cozy vintage bedroom with soft ambiance lighting created from tree branches and repurposed string lighting. Just so sweet!
