I'm another that got most of my sewing experience with garment construction before moving on to quilting, so bias does not give me any fits. I do have to pay attention if I'd dealing with bias, but I don't worry about having a bias edge if I cut a square in half or something like that.
I've got a lot of sewing machines, and some really do not deal with bias very well. I often wonder how much of the difficulty some people have is because of the machine they are trying to do it on.
