Do you wish to add a touch of realism or flat-out whimsy to your fairy gardens? Though those are two entirely different goals, you can make either a reality by adding fairy mailboxes to any garden. Whether you opt for a very realistic and somewhat standard miniature mailbox, with the red flag to raise when you have outgoing mail, or a far more rustic and fairytale design, it is a touch that can really bring fairy gardens to life.
