Do all ogham staves have to end with that V symbol like this picture: http://www.spiritofold.co.uk/images/divination%20-%20D080%20corresponding%20ogham%207.jpg (Remember to take out the space, if their is one, in the link for it to work) I made my staves without it and I just wanted to know if it was okay. Why do some people do the V thing?
