I remember reading about this somewhere a while back and from what I can remember is more a fact of fashion or trend more than if it can be done. I have seen older quilts with a very wide binding, some with the binding filled with batting and some with it not filled. Making it narrow is easier because we are used to the 1/4 inch seam allowance, since we have the foot for it, but doing it wider is possible if you mark it properly. You also need to think about it ahead of time while building the quilt, especially if you don't plan to add a border. You may end up covering part of the block. If there is a wide border it will not be a problem.
