I can see you bringing the bobbin thread to the top just to get it out of the way, but when finishing the quilt, I would bring both threads to the bottom, knot it and bury about 2" inside the quilt. If I'm putting hard work into the quilt, I'm going to do everything I can to make sure the thread ends are secure, just as the ube quilter says. :)
