Abstract
A sewing machine includes a control portion that controls a thread tension adjustment portion and a feed portion such that a first stitch and a second stitch are formed alternately on a sewing object. The first stitch includes only a stitch in which an interlacing point of the upper thread and a bobbin thread is lower than a top surface of the sewing object. The second stitch includes at least one set of a first section and a second section. The first section is a section in which the interlacing point and the bobbin thread are pulled out, by the thread tension, in the first direction on the top surface of the sewing object. The second section is a section in which the bobbin thread is pulled out in the second direction, and at least part of the second section overlapping with the first section.
