What is the best way to securely hang a wall hanging using nails?

To securely hang a wall hanging using nails, first choose the appropriate size and type of nail for the weight of the hanging. Locate a stud in the wall for added support, then hammer the nail at a slight upward angle into the stud. Ensure the nail is driven in securely and hang the wall hanging on the nail. Use multiple nails for larger or heavier hangings for added stability.
