The most common way to hang is to hold the mirror or picture against the wall where you want it to be, have someone else step back and level the item from sight, and then mark the wall with a pencil where the hangers should be. A level can be used to make sure the item is perfectly straight before the wall is marked. On the largest Modest Hut mirrors, we provide a self-leveling adjustable J-hook. With this hardware, if the item is slightly uneven, the hangers can be adjusted without moving the nails from the wall.
