bearisgray, AMEN TO THAT!
Accurate piecing means you aren't trimming up blocks only to find that points are cut off or other mismatches occur and then puzzling out what to do about it.
When I was just starting out, a Board member here, MTS, recommended I read Sally Collins' book on machine piecing and I did. It is not just a technique book, it is a philosophy and it totally changed how I was piecing - new attitude, perspective about precision. Neither patience nor precision were particular virtues of mine, but I have learned them through quilting
