It's your project, stress over it if you must, just don't stress over the stressing! :-P
I'm a Virgo and we can be really, really intensly exacting. The Perfectionist. But I learned to not demand exactness in everything when I volunteered at an elementary school and had to make seasonal posters for the classrooms. It dawned on me pretty fast that the wonderful children enjoyed the entire picture, never noticing that the circle might not be perfectly round at one area. If something really is obviously off, I redo it. Mostly I remind myself that I quilt the Amish way, No one is perfect, only the Lord is. Works.
