If your method of hanging pictures and paintings involves asking a patient friend 20 times about crookedness, an Apartment Therapy blog reader would like to, er, set you straight with a guide on getting perfectly aligned frames.
If you can't commit to a single bit of art to adorn the entire length of your couch, or vertical span of a blank space, hanging multiple frames is a great idea. Apartment Therapy reader Rainer details his methods for hanging nine frames in a perfect grid, centred on the wall and in good proportion to other room elements:
If you already have the artwork and want to make sure it hangs just perfect use masking tape to outline the position on your wall. Play with the outline to get ideas of how it will look when you walk into the room or how the light will interact with your art.
Once you establish your favourite spot you can use the masking tape to hang the works precisely. With two inch masking tape you have enough room to eyeball the overall position and then measure and mark the final nail/screw spot.
Rainer recommends the purchase of a suction-cup-mounted laser level, about $US20, to avoid mistakes and speed up the alignment process. Have you got a non-laser-guided levelling and hanging system you've used in the past? Tell us about it in the comments.
