I'm doing BOMs and some months are challenging. My July block I just finished and it was pieced and the outside was pp. The inside was suppose to be 8 1/2" but mine ended up being 9" so the paper piecing wouldn't fit. I ripped it apart and started over and got it down to 8 3/4". I made the paper piecing larger than called for and put it all together and it's suppose to be 12 1/2" and mine was 12". How can that be??? It's crazy! So I put a border around it and called it good. I hate ripping.
