My garage (Man cave). Used reclaimed barn wood and door hardware to create slider to cover the windows. The walls are made from new lumber and distressed (found the idea on here, thanks). The shelf and tin is also reclaimed.
Forget the headboard part 2....or do the whole wall in corrugated tin!! You can use rusty tin and then use an aging glaze over the top for a rustic look, or keep it shiny for a more industrial look. It can also be painted any color you want (think red, bright teal, pale yellow.....). Really the possibilites are endless...in any room of the house!!
