As an untrained and naive artist I learned a very interesting lesson over at http://carriejoyart.blogspot.com/about The Golden Ratio. This was new to me and very informative. I am striving to utilize this in my works. For most of you artist this is nothing new but for those who don't know about the Golden Ratio you will find this a useful lesson. Stop over and check it out. Thanks Carrie..I'm an old dog trying to learn new tricks and this is a good one.
