As you can see...there are lots of answers to this question. It really depends on the quilt.
Best thing to do and "what we're here for", especially for a new quilter, is to work on your quilt and ASK this question and other question you have.
We have ALL been there and know how you might feel "like it might be a "stupid" question. In quilting, there are NO stupid questions and, believe it or not, even the experienced can learn something new. It might be something we never did for one of projects.
