Step 4: Step 3- attach
I found that using picture hanger things was invisible and didn't harm my wood. I got these at Wal-Mart for $1.99.
On your pencil marks, attach the picture hanger things to your wood.
Put screws in the wall on your wall marks. We had to use alligator drywall anchors because our hanger things didn't match up with any studs.
Now you are ready to hang!
