I found that this works really well for me, being as my element is Air, and feathers represent that. :)
In natural magic feathers are used in spells and ceremonies to promote change. They are used as catalysts to help focus concentration while carrying out spells and wishes.
The medicine bag, also called power pouch or sachet, often includes special feathers which have meaning to the wearer and help attracting good luck as well as driving away bad things.
Feathers are often used to focus concentration in spells.
Feathers are magically ruled by the element of air. This makes them good communication helpers. But each feather also can hold other special powers; depending on the bird it came from, its color and place of discovery and other factors.
The knowledge what kind of feather is best used for what kind of indent can only be found out for oneself by trial and error. A pigeon feather is not as helpful for creating a defense strategy than a feather taken from a bird of prey.
The general rule for future feather magicians is always to use self found feathers rather than bought ones. A shop cannot substitute a walk in nature, nor the joy when the wanted feather is finally found.
Feathers are often used to focus concentration in spells. Feathers used for magical undertakings are mainly determined by the energy which is brought into the feather by the magician him/herself through concentration and thought. Beside from the energy the magician brings into the object, feathers hold certain natural abilities.
