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 :)
I could see adding a higher wood bar like this onto our new island. Modern Home by Gardner Mohr Architects. this is unique! i've never seen an island corner structured that way. gives nice geometric flow.
