If your quilt is going to a show, that could be a problem. If it's going to a family member or friend, or a charity, the recipient will bless you profusely and show it off with pride, and no one in their world will notice whether a few seams don't match up - even (gasp!) whether you've cut off a point or 10. I've never had one given back! And, as my best friend says, quilts aren't supposed to be perfect - and she should know, she has a whole collection made by various ancestors!
Also, try starching the heck out of everything
