Umm hi everyone. I'm actually here for advice. I've wanted to get a custom sterling necklace with japanese character...symbols...on a necklace. I know what I want to put on there - either my nickname "Liz", my full name "Elizabeth" or the name of my priestess OC named "Akiko" (which I also count as Japanese name since I AM in fact an autumn child) Right now I'm leaning towards wanting to put "Liz" or "Akiko" on it.

Do any of you know of some good websites that do this kind of thing? And can anyone help decide what form it should be in like Kanji or Katakara....(or whatever its called)

You could try this
www.cs.technion.ac.il/~danken/kanjidic.html

But i'm not sure if it works with names. You may need to search the direct translation of your chosen Japanese name because I'm not sure if you can Kanji-fy english romaji.

you can go to http://www.mycosplayclub.com
