Rune magic is a Germanic religious practice done by Teutonic tribes of ancient times and modern Ásatrú groups. Runic magic is the active principle as opposed to the interpretation based on Runic divination. It is more active than say the shamanic rites undergone in Germanic paganism known as seidth-craft. And it is also in stark contrast to the prophet and prophetess known as the spakona (female); and spamadhr (male). Runic magic, in practice, deals with the runes and using them to affect the world outside based on the archetypes they represent.
Most of runic magic entails being in possession of a physical entity (whether bought or made yourself) that is engraved with any or all of the individual runes; also known as staves when physical, so as to practically work with their so called energies.
After possessing the staves, it is common to redden the individual characters of the Futhark with either blood or store bought dyes or paints. In traditional Old Norse culture it was perhaps more common than not to have them reddened with blood; but in modern times dyeing the runes is also accepted as a necessary means to an end.
The act of having the stave in its final form, in runic magic, serves the purpose of affecting the world of form with "the rune might" of that particular stave. After you have purposefully used a rune you have made yourself, and allowing the idea of being satisfied with its effects, it is common to somehow discard of the stave; whether it be burned or what have you.
