mail stationery in Lion

I had a letter that I wanted to save for future reuse and followed the instructions to save it as Stationery. It was done in Pages and it was saved as Stationery in Mail. I just went to reuse it = opened new message, found the email template and clicked on it = nothing happened other than the subject line was entered. No body. I clicked on other types of stationery and they all show up as a template. How do I get this email to become regular stationery? How do I get it to work?
