Drawing just one rune is the easiest and probably the most common method of reading. Without a storyline like when interpreting a layout, there are no runes to compare and contrast. Simply interpret the rune as the answer to the question.
Alternatively, this method may be used repeatedly in succession to allow the runes to tell a story.
This is a lucky time for you. Perthro is sometimes called "Gambler's Rune." It is symbolic of clarity of purpose and ambitious drive. Mysteries will be revealed. Be certain to take advantage of these times.
