Remove labels from empty Moccona jars. Wash and dry jars.
Position a key ring halfway along a 120cm length of picture wire. Thread both ends of the wire through the ring (in opposite directions) to secure in place.
Place ring just under the lip of the jar, on the side furthest from you. Wrap wire around jar in both directions, crossing at the front. When the wires meet again at the back, cross each wire over, then under, the ring.
Wrap wire around the jar lip again, crossing wires under, then over, the ring at the back. Twist ends of the wire to secure, and trim excess if necessary.
Half-fill jar with water and add plant cuttings or fresh flowers. Use the ring to hang jar on a secure wall hook.
