Want to hang a large picture in our apartment dinning room?
You can hang it on large nails nailed into studs. If studs aren't an option, you can hang it on screws and drywall anchors rated for the appropriate weight
My favorite pieces of hardware to use for hanging picture or mirrors are auger anchors. Here is a post detailing them and how to install them. Hope this helps!
French cleats, also called Z bars, are another hardware option for hanging heavy pictures.
