I just completed a couple of new templates that allow display of Tengwar characters. Due to a limitation in the wikicode there are 2 templates: Template:Tengwar and Template:Tengwar2.
Tengwar displays only a single character but can be resized.
Tengwar2 can display multiple characters with a single call but cannot be resized.
{{Tengwar|1|px=50}}
{{Tengwar2|1,2,3,20}}
Feel free to use them in articles, guides or on your User: page.
