It's that simple:
Enlarge the template to 200% or design your own template freehand. Rework the single elements with the thick aluminium wire on the template, but bend the narrow windings at the beginning and at the end with the round nose pliers, the rest by hand.
Wrap all parts at the points marked in the template first with adhesive tape, then with fine wire.
Wrap the tea light glasses with the thick aluminium wire, starting with a small spiral around the tip and increasing the distances upwards.
Bring the wire together to form a knot, leave a longer piece and bend it into a hook. Secure the junction with fine wire, hang the Tealight holders and wire it tight.
Make small spirals out of the remaining wire and glue them on some joints for decoration.
Extra handicraft tip:
Instead of the tealight glasses, decorative test tubes can also be hung on the wall decoration. Use these as vases for single flowers.
