Hi guys. Though I am a girl who has a deep love of Tolkien's work, I
have very little knowledge of his work with languages and while
attempting to research, I've come out with contradictory information.
Basically I'm confused as all hell and need some help.

I'm trying to get a memorial tattoo for a dear friend of mine who died
a year ago. I want to get it of his name (Andy) in Elvish, but no I
don't really know what KIND of elvish/Tolkien writing I want, so
basically I want to know what my options are. It's very important to
me that I get this right.

The first version that I found was this, which seemed to lay it out
pretty simply:
http://www.starchamber.com/paracelsus/elvish/elvish-in-ten-minutes.html
(they used the name andy as an example. how convenient!)

However, a few sites (such as this one:
http://tengwar.art.pl/tengwar/ott/start.php?l=en) that I've seen since
have had all the same characters, but all in different positions, and
I can't tell which is correct.

Does anyone have any suggestions/ideas for what would look best AND be
most accurate? I'm fairly sure I don't want an actual translation of
his name into elvish, just the letter-by-letter version, but I
probably could be swayed. Any particular Tolkien language that you
think would be best for my purposes? Any other assorted suggestions?

Thank you so much. Any help is greatly appreciated.
