Kate, Christina and I are doing it together and we found the simplest way is strides. I though it was a good choice because it is quick and easy. One downside is that like Tianna said the slightest mis calculation could mess us up. In the end i am happy with our choice! Us three work well together, one thig that i am glad about is that we dont have to sit there with a measureing tape moveing from wall to wall.
