bookcase made from bi-fold doors at My Repurposed Life -- great idea! I'm taking my bi-fold door off both closets soon and replacing with curtains; could use one set to make skinny bookcase for one side of bed instead of bedside table.
Corner shelf made with an old door. Cut door in half, screwed in brackets to hold it at 90 degrees, and then cut shelves to fit and secured those with brackets also.(((( awkward corner in dining room ?))))) (((( or living room.
