This is a non computerized heavy duty machine that is referred to as a school machine. It has 18 built in stitch patterns, automatic buttonhole, a wide stitch width at 7mm and a built in needle threader. It comes with a hard cover and has a convertible free arm. Along with the 7 accessory feet that came with it, I am including a free motion foot and a dual feed foot. This was bought to carry to classes so has had very little use.
