I have been thinking of putting a couple of Runes on my body in form of a tattoo.  

I tried searching around online to see if this is a wise thing to do or would cause some sort of backlash or otherwise be a bad idea.

Anyone have thoughts on it?

Thanks

I suspect it depends on what you want the runes to do or say.  I would go with a rune that generally is not subject to negative interpretation (unless that is what you want).  Runes that promote positive feelings and well being would be best.  If you wanted Sowilo, for example, please be aware that this rune got a bad reputation in that it was used by the Nazis for the SS in World War 2.  Of course, that is a case of Nazism misusing the Germanic heritage (in extreme) but thought it was worth mentioning.  Personally, I am happy wearing a symbol round my neck of the rune, and that may be the best place to start, before you commit to something that is harder to reverse.

If there is one rune you are particularly drawn to, I think it would bring you only positive things

I am not brave enough to get a tattoo (don´t like needles!) I don´t actually like tattoos either but that´s neither here nor there.

If it feels right... do it.

Not all runes are created equal.  Isa is generally a not overly positive rune, even in its most positive interpretation.  (Also boring from a tattoo perspective, I suspect, looking like the letter I).  Translated as ice it refers to delays, frustration of plans, and stillness.  Of course if life is crazy and you want to slow it down, well, I suppose Isa is the rune someone would want.  What I was counseling was mostly getting to know the rune before committing to needle and ink.

Odin, All Father
All seeing, all wise
Whose knowledge is gleaned
from the Earth, seas and skies
Help me evoke
the power of this rune
May it act as a lodestone
and bring me a boon.

Like any tattoo it is permanent, try getting it done in Henna first and see what repercussion you get from it.  Henna tattoos are great and if you get sick of that rune it will eventually wash off and you can apply a different one next time.  Just remember the colour is also the key to how powerful you make this rune.  Red symbolises blood I guess so it would probably be more powerful too you.  Like some of the other post before me I would stear clear of negative runes and definately do your research before choosing anything permanent.
