There are a lot of varying opinions on this. We had a quilt judge that spoke at our guild meeting who said she never used bias, that most people can't get it "right", and it didn't matter. On the other hand, I've always done bias, and have always gotten good comments on my bindings when entered in shows. I like the fact that you can stretch it a little as you sew it down, so it pulls in the edge of the quilt just a hair. If you want to do any curved corners -- like around the bottom two corners of a bed quilt -- the stretch you get from the bias makes that easy to do. ANd if you have lots of curves -- like a scalloped edge -- you pretty much have to use bias binding.
