Lay all your pieces of artwork out on the floor in the arrangement you want for your gallery wall. Play around with the spacing and positioning until you like what you see.
What’s your anchor piece? Your anchor piece is usually your largest picture or art piece but could also be the center of your arrangement, so hang that piece first.
Start by identifying an easy reference point on your anchor piece. An edge is usually the easiest but depending on your layout, it could be the center or maybe a part of the art itself.
