I agree, getting the piecing "perfect" is always a problem with me. Even when I square up each block before sewing it to the next block. I have found that it helps some to place a piece of masking tape on my sewing machine 1/4 inch right of the needle extending it all the way out to the edge of my machine to give me a "line" for my fabric to follow so I can get a true 1/4 inch seam.
