Seasoned woodworkers might sniff at a tool that helps you hang pictures, but when they see how simple it makes the process, they'll be impressed, too. Whether for wall shelves with multiple keyhole fasteners, multiple D-rings or just an ordinary wood frame on a nail, the process is the same: stick the DOT target markers onto the hanging, press the hanging against the wall in the desired position, and the little bulls eyes will adhere themselves to the wall in the exact location where you need your nails or screws. No more tape measures or pencil marks -just position and press. And best of all they are reusable, you can hang an entire houseful of pictures with one package. The kit even includes a stick-on level so you don't have to juggle a heavier one while you get the position right.
