And my point is, if it's being done correctly, there should be no need to any "trimming" or "tugging" or "adjusting" of the binding/batting/quilt top.
So trimming here isn't going to solve the problem on her next quilt - or even her next corner.
Doing it right isn't any harder than doing it wrong. And that has nothing to do with the quilt police.
We just need to figure out where the op is having a problem - perhaps is not aware of a technique or method - and advise her accordingly.
