A cheap (new or used) door can make a good headboard. Laid on it's "side" of course and attached to the wall. Gardening fencing (iron, metal), or garden decorations of metal (2 or 3) look good also. Just attach to the wall.

My daughter and her husband have a huge bed and when the moved they needed a headboard. They decided to make it themselves.
This is not only decorating, but crafty as well. I had an older style futon for a bed frame, and it was black shiny metal. Not conducive to a nice lilac and mint green bedroom.
I used a wooden drapery rod to make a holder for fabric or a quilt or bedspread to use as a headboard. It is cheap, fast, and can be changed quickly.
