Dude... you're stressing me out! lol
Mine weren't "perfect" either, now you've got me worried they won't be acceptable. They were well under the 1/8th margin, and the points were pretty spot on, although not all exact. I think they were pretty good, and I'm pleased with them.
You're being wayyyy too hard on yourself. Keep in mind too that once put together with a whole lot of other blocks, and its quilted, tiny little imperfections are not going to be noticed.
