Beside using newsprint to gauge furniture placement, you can use it to determine layout of pictures/art before you take hammer to nail.
Just measure and cut your newsprint to the size of the pictures/art you want to display. Tape and, better yet, RE-tape them to the wall of your choosing until you have them in the positions desired. And then hammer away. This also works great if you’re using those marvelous 3M Command Hooks. No need to waste the sticky part just because you have trouble with spacial placement.
Now that’s a good idea.
