Various ways of writing "Om mani padme hum"?

[M1NDFUL]

I'm not really sure how tattoos are viewed in traditional Buddhism, but prior to taking my practice seriously I covered myself in ink. I would like to have this mantra tattooed on my body to signify this new chapter in my life going forward. I'd like to know if it is still proper for this mantra to be written right side up, but typed going downwards vertically? I hope that makes sense.

Gassho,

Welcome
I've seen lots of OmManiPadmaHum tattoos, but never a vertical one. On the other hand 'OmAhHum' goes vertically...

As for tattoos in Buddhism, they are mainly a feature of the Theravada tradition (google: 'sak yant')
(never, ever get one of these unless it is from a well respected monk!)
