I am trying to design a logo but I want the base to be a shield/crest. I messed around with trying to develop one but I could get the edges even, smooth, and rounded over the whole crest. Below is a link to a style of shield I would like to use but I want to make my own and not just download someone's work. All I need is a way to draw the outline of the shield, I will handle the coloring and center my self. I just need a technique to draw a perfectly measured shield outline.
