I haven't read all the comments, but would say turn the top and bottom to point in and to match the sides. Then let it go. Admittedly, it's easy for me to say that about someone else's work! I'd probably rip and turn the sides if it were mine, but, as others have said, that's my hangup.
The quilt is beautiful! You did a wonderful job. Where, might I ask, did you get the pattern and materials? Is it a kit. Since I live in Seattle, I'd like to check it out. I'm wanting to make a sampler, but haven't settled on a pattern yet. When I do, I hope mine turns out as well as yours did.
