The Singer Heavy Duty machine lives up to it's name! I've made several hundred masks for First Responders during this COVID crisis using an old sewing machine. How great to have this one that sews over the pleats in the mask without missing a stitch. No more fighting to get the fabric to go thru. Love it. Don't love the small light focused directly on the needle. Don't like the placement or the feel of the reverse switch, but I will get used to that.
