I think it looks really beautiful!! I'm like you though...it really bugs me when I can't get something "just right." After asking this board for help, they reminded me that nothing is perfect and of "humility" blocks. Helps put things in perspective, especially when you know the person you make it for will appreciate it--errors or not. My husband says I over think things and that an untrained eye won't notice things, especially when its all put together.
Of course, I still go back and forth with my seam ripper and at some point just have to throw the towel in and say that perfection will just have to come with time....
