Blessed Pen

First begin by finding the right pen you want to use. You might take a trip to the store and just look for a pen that "sticks out" to you. When you hold it, you will know its the right one you want to use. This pen will be used only for magical purposes, such as writing in a BoS or writing a spell on paper. 

Make holy water (or collect rain water) in a jar. Let the pen sit in the jar for a day and a night. Once the pen is done soaking, hold the pen in your hands. Place it on your altar and say, "I bless this pen in the name of (Goddess)".
