I will admit that I am the worst at hanging pictures on the wall. It's taken me years to get sort of good at it and not make 10 holes to hang one picture. And I will be honest, I'm probably still pretty bad at it.
But with a picture frame that has 2 hooks, you can use tape to measure the distance to place the nails.
Simply place the tape on the two hooks as pictured and poke holes where the nails should go.
From there, take the tape, place it on the wall, and nail away! The picture I have hanging is actually canvas art framed that my little/bestie made for me. She knew/knows that I am obsessed with antlers right now :)
