Do you have problems hanging your pictures where you want them? Do your wall groupings look like they were hung by a blind man? Do your walls look like this?
Here's a really simple solution that I've been using for several years now. I call it my "Pix Stick".
All you need is a paint stick and a screw or nail (like my artwork?).
As you can see, there's a screw "screwed" into one end of the stick.
K, here's the back of a picture frame. Locate the picture "hanger".
Another common hanger is a sawtooth hanger. (not all hangers look the same but the pix stick will work with all types of hangers)
It should look like this.
Here I am pressing firmly against the frame at about the area of the screw to make a small mark on the wall.
The mark made by the screw is exactly where you will be putting your nail in the wall to hang your picture.
