I've been meaning to tell you guys about this for a while and I keep forgetting. Have you heard of the "World's Smallest Postal Service"? It's a genius idea, and I think I'll be ordering some of these in the near future- perhaps a letter from the Tooth Fairy (comes with fairy dust!).
Here's a description from their own website:
The World's Smallest Postal Service is a teeny tiny letter transcription service - now available online. Here's how it works: You write a letter... and it is transcribed onto tiny stationary (1 x 1.5 inches) with a magical transcription device (see example to the left). It then goes into a tiny envelope which gets addressed, stamped, and sealed with a miniscule wax seal with your initial on it. The letter then goes into a see-through folded coin case and is packaged up with a magnifying glass in a larger glassine envelope, finished off with a large "World's Smallest Letter" wax seal. It is put in a sturdy mailer for shipping.
