Don't be discouraged. I have learned that a common fault of all quilters is to want perfection and since we are only human, we can't be perfect. Nick will love it because you spent so much time and effort on it. Not everyone is lucky enough to receive a gift as special as a quilt, and that speaks a whole lot louder than any imperfections you see. I generally like my projects until I start quilting, but looking at a project up close for so long, I tend to spot the least little flaw. Then I tell myself that it isn't worth enough to be given as a gift , where as the receipient never even notices those things. They are usually just so touched that you think enough of them to do something so nice for them. So don't beat yourself up. This was a very big undertaking and you should be very proud that you got this far. And Nick will be thrilled just wait and see.
