Practice, practice, practice. If you only tried it once you need to try some more. I put all my bindings on by machine and I will say in the beginning they were not good. Now I bind for people when I longarm there quilts and they love it. Practice on charity quilts. Also, I don't press my binding in half. I just fold and attach to the front. When you roll to the back, it will make its on "edge" and fit in better. Good Luck.
