To organise multiple pieces of art in a row or gallery-type display, Sauer recommends some forward planning. Her trick is to roll a large sheet of paper to the size of the space she’d like to fill with art. She places the sheet on the floor and shifts around her picture frames until she finds a setup she likes (she recommends keeping around 2-5cm between smaller frames, and 5-8cm between larger ones). Sauer then traces each frame and marks where each nail needs to go to hang them. She then tapes the sheet of paper to the wall, puts all the nails in where the dots are, and tears the paper down. Hang the frames and your gallery is complete. Got a few frames that just won’t stay straight? “Put a small piece of Velcro or a command strip onto the bottom of the frame so it doesn’t tilt sideways,” Sauer says.
