Mobiles look great when paired side by side, here with the pistachio and ivory 'lantern' and its shadow version in matte black.
Hanging recommendation: Stagger the pieces in height to create contrast (with the fishing line that will come in the package), and separate them just far enough so that they can each rotate without catching each other.
