A headboard can really be a great focal point for a bedroom, and just because you own a regular ol' bed doesn't mean it can't have a regal backdrop. So if you don't own a headboard, why not try painting one on?
I'm loving this idea from Point Click Home, and it would be very easy to recreate. Simply paint a block of color the width of the bed, and add a small stencil in another shade for a fun bit of detailing. Has anyone tried this at home? If so I'd love to hear about it.
