"First assemble your material," Paula writes,"You will need a large sturdy terra-cotta pot as a base, a large dry florist's foam ball (gray or brown), florist's dry-hard clay and some lengths of florists stub wire for wiring some of the ingredients so they can be inserted into the foam and held securely.
Place a lump of dry-hard clay inside the terra-cotta pot, making sure that you fill the pot to approximately 2" (5 cm) below the rim so that the base of the topiary tree is stable. Because of the height of the arrangement, it will topple over if it is not bottom heavy.

Group together bunches of sage, dried copper beech leaves and marjoram or oregano by binding the short stems with wire and inserting into the foam. Take some dried maize, wire one end with heavy gauge wire and insert. wire balls of green tagliatelle and insert (this has to done with care as the pasta may break. Cut the stems of the thistles short and insert them directly into the ball.

Tie some sticks of liquorice into a bundle using a length of stick. Carefully wire balls of pink tagliatelle and add them to the foam. Wire and add bunches of millet.

Continue to cover the surface of the foam, keeping an even all-round covering of decorative material. Infill any gaps- no part of the ball should be visible.If you prefer you can first cover the entire ball with moss pinning it with U shaped pins, this ensures all the foam is covered.

Fill the pot with pistachio nuts and star shaped dried aniseed so the dry-hard clay is concealed."

She says,"This  delicate topiary tree would make a wonderful gift. A cluster of cinnamon sticks has been placed in a weathered treeacotta pot, then a ball of floral foam has been taped on top of the sticks and decorated with hypericum berries, holly leaves, gilded pine cones and roses."

"The general shortage of raw material in winter makes this an excellent time for using long lasting flowers , such as chrysanthemum, carnations, and Dendrobium orchids, You can also gild gold and silver seed heads and twigs which retain their shape in warm rooms as they are already dehydrated, and use ribbon and rope decoratively to make up for any lack in floral colour."
