Did your family want to mail you a life size ceramic lepracan for St. Patrick's Day but didn't because they wondered

 a) if that was okay and

b) how much it would cost? 

Mine didn't either... *but if they had,*   they could have looked at website:http://pe.usps.gov/text/Imm/immicl/immicltz_009.html 

It gives a detailed list of costs and restrictions. 

By the way, it's my understanding that a life size lepracan would still be pretty tiny.

Thanks for pointing me toward this, Kyle!
