Hold 1 pin with pliers, and bend it 90 degrees with your fingers. Cut a 4-foot length of silver cord. (If you want your chandelier to hang higher, cut shorter lengths; for lower, cut longer.) Knot 1 end of cord around the bend in pin. Dab with glue at knot to secure. Feed pin into hole in 1 glass ball. Once pin is inside, gently pull cord to position. Repeat with remaining glass balls.
Working over a soft surface, arrange balls in a cluster: Start by grasping just a few in one hand, and adjust the length to form a cluster of varying lengths. Add single balls as you go, adjusting length as you wish and adding the cord to the cluster you’re grasping.
Thread the loose ends through washer, and tie a knot, leaving a tail of about 18 inches. Optional: Wrap tail around washer to cover it completely. Secure with fabric glue. Hang from a hook anchored in the ceiling.
