Before you start, collect as many ideas about existing mobiles as possible. Searching the internet for "Calder mobiles" is a good way to begin. Calder was an important modern artist who made this type of mobile popular. Several modern art museums exhibit some of his mobiles.
To make the mobiles more complex, you can vary the shape and size of the wood pieces, the side to which you attach one arm to the next, the curvature of the wire, and by hanging the mobile or allowing it to stand on its own.
Exercise proper safety precautions when using workshop and power equipment.
Things You'll Need:
- Needle-nose pliers
- Wire (hardware stores sell 200ft rolls of galvanized wire)
- Sheet of 1/2" ply wood for the weights or shapes at the end of the wires
- Drill and bit (same diameter as the wire)
- Clamp to hold the wood pieces when drilling
- Jig saw to cut out the wood pieces.
