Cutest office gift ever: Hearts & hyacinths. "forced" bulbs for the holidays. Amaryllis with white hyacinth & red tulips in a clear container with just stones and water, no dirt. Then tie a beautiful ribbon around it.
Another reason to have some silver angel hair and red wire in your flower arranging tool kit. Add three red roses and a few sprigs of green, all you need is a small glass and you have a quite simple arrangement.
