If you find a white feather take it up and say your own name, as you do than the name of someone you like, if there is one. Or, simply say "loves token." if there is no one special in your life at the moemnt.
If you have someone in your heart, place the feather next to a photo of him or her and promise to give love:
light as a feather, soft as silk, uplifing as a cloud
Take these words seriosuly: a feather used in a spell really demands that you are not too heavy with someone you care for, and that you are reasonable in your handling and expectation of the other person.
If you have no one in your heart, place the feather against a photo of yourself and speak to the angels about your need for someone to enter your life and lighten your heart. Pledge not to make heavy demands on them.
