I totally agree. I have never tried for my quilts to be perfect. I figure it this way, I sew for a stress relief not to add more. And honestly one of my favorite quilts I made, has 6" sashing because when I tried to trim the blocks none of them matched. And honestly every time I look at that quilt I smile. My theory is if more that three corners match on a block, I'm trying to show off. LOL
