Trim the base of the branches. Bring them close to the head to check how much you need to trim them and at what angle.

Apply a small amount of glue on the florist wires. Insert them in the branches (rotary motion; to about 1/3 length).

If the branches are losing shape while inserting the wire it means that the paste is too soft. Leave them to dry for a little longer.

Trim the wires so that they stick out about 1-2 cm.

Use a spare piece of wire to make tunnels in the head (at the same angle you want to attach the branches).
