Wow! My first thought was how lovely and consistent your stitches are - that is very hard to do! Can't believe you haven't done it before! Like was said, you may find when fmq in the border that it is more densely quilted than your cross hatching so the feel will be different...you can do what you want but I've read that the quilting should try to be 'balanced' all over the quilt. Yes, I'm curious what kind of thread you used??? Beautiful job, you should be VERY proud of yourself. And the only way to learn is to just do it!
