Tips on how to hang the perfect gallery wall 1. Frame Arrangement: Lay out the frames on the floor to determine your desired composition. 2. Create paper cutouts of your frames: lay your frames out on paper, trace around the outside, and cut out the shapes. Note which cutout goes with which frame. 3. Locate hook location: Hold the wire taught and measure from the top edge to the center point of the wire. Make a mark on the cutout where the hook catches the wire. 4. Tape cutouts to the wall, with painters/masking tape, mimicking the arrangement on the floor. If you do not like how it looks on your wall, repeat step 1 and then skip to step 4. 5. Final details: Adjust cutouts until all pieces are lined up exactly as you like. 6. Hammer the hooks in where indicated on the paper, remove the cutouts, and hang frames. You should be left with the perfect gallery wall, no re-nailing or measuring needed.
