Some machines perform so nicely with thicker fabrics. The Davis NVF is that type of workhorse. Just give it layers of denim along with the layer of cotton binding and batting for it to show how well it can handle the job. Very pretty stitches with all that thickness. I knew the Davis NVF glides through flannel. It loves denim!! I'm right now binding a mock cathedral quilt made with used jeans. I love my Davis!!!
