Rotary cutting has revolutionised patchwork, making it possible to cut and piece accurate blocks. Be absolutely, totally, over-the-top, utterly and completely obsessive about cutting out. Together with a good 1/4" foot on your sewing machine, or by placing an accurate mark on the sewing machine bed if you don't have a 1/4" foot, this will make pieced patchwork a delight. The more accurate the cutting, the better the piecing will be. The better the piecing, the easier it will come together. The easier it will come together the more enjoyable it will be. And of course, the better will be the results too! Happy quilting.
