In the first two pictures, the main problem is the curves are very severe. It won't matter what binding you use, the binding on those tight curves will always do that. I don't know what the problem is on the last picture, that should have worked out fine. What is the binding made of? Do you have any padding under the outside edges that curve down? If you don't, eventually you will have wrinkle problems on the main top there too. Regular convertible tops have cables that hold the curve taught and also prevent the top from getting damaged by the air flow while driving.
No one lives forever, the trick is creating something that will.
