My daughter and I both learned our lesson (which I knew but wasn't thinking) about the grain on my AccuQuilt, at different times. I couldn't figure out why some of my squares were the correct size and others were smaller. It took me a while to realize it was the way I laid them on the cutter, with the grain going the wrong way and you roll it thru the cutter it stretches the fabric while cutting and then it goes back once cut. My daughters experience was about the same thing, she's new to sewing and only does block quilts but knows this lesson. Its better than the first time she made a quilt, she cut out a square, then held in the fabric in her hands while cutting the rest of the squares, to say she had a lot of uneven squares was an understatement. But she learned her lesson and it took some work but I finally got it all to work out. We all have to learn and some times be reminded again on things when it comes to sewing and life
