Gather supplies. I used electrical tape since that is what I had close by. I recommend using masking or painters tape, something that does not stretch out of shape.
Turn picture to the backside. Unroll tape and line up a piece of tape from the middle of one side of hanger to the middle of the other.
Middle of hanger
Cut after unrolling tape to size
Remove tape from picture and put on the wall where you want to hang the picture.
Hammer a nail at the top edge of one side of tape....
And then a nail on the other side.
Works like a charm every time!
