HGTV says if you mix a gallon of glue with glitter, then paint with it, the glue will dry clear... Bam!! Glitter wall!! I have to do this in someone's room?!!! (Andy will kill me for painting AGAIN -hehe)
I know I'm too old to love this but I can't help it lol... 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.
