Inside was a teeny tiny card, with a letter to the children written inside. The letter was from the Elves and Fairies, who confessed that they had secretly been playing in the children's garden every night, and particularly enjoyed the new cubby house. They hoped that this was ok, and promised to put all the toys back exactly where they had found them so nothing would get lost.
The Elves and Fairies also promised that if the children left them a letter in their toy postbox, they would write back. And would Ralph and Scout like the Elves and Fairies to send them a present? They would be happy to do that, as long as the children understood that the present would have to be very, very small (or else it would be too heavy to post).
This was an adorable little letter, with attention paid even to the tiniest detail. It came in a little glassine envelope (with its own wax seal) alongside a magnifying glass for reading the letter. I ordered it from Leafcutter Designs, and the whole thing cost $US9.75 plus postage, which I think was quite the bargain.
