Done is better than perfect. Quilting is something I do for fun and relaxation. I refuse to torture myself because something is off a little bit. People that don't quilt will never notice if a point or two are cut off or don't match up perfectly plus that's the kind of thing that gives a quilt personality.
Don't obsess, just sew!!
I've even left wrong side out fabric in scrappy log cabin blocks. After the quilts were done *I* coudn't even find it!!!
