Abstract: A circular stitching device for a sewing machine includes a body base attachable to a sewing bed or an upper surface of a needle plate, a movable base located on the body base so as to be movable in a predetermined direction, a cloth fixing member including a cloth-fixing pin which is passable through a workpiece cloth and is formed with an engagement portion, and a holder holding a proximal end of the cloth-fixing pin, a cloth-fixing pin support detachably attachable to the movable base thereby to support the cloth fixing member so that the cloth fixing member is detachably attachable thereto, and a locking unit which is located on the cloth-fixing pin support and is disengageably engageable with the engagement portion of the cloth-fixing pin, thereby locking the cloth-fixing pin.

Abstract: A template for circular sewing is used for repeatedly sewing a single pattern into a circular arrangement with use of a sewing machine equipped with a circular sewing device. The template includes a transparent sheet member having a center point, a plurality of arc-shaped base lines arranged in a concentric pattern about the center point of the sheet member, and a plurality of linear pattern pitch measurement lines which are provided for measuring a pitch of the patterns and which are arranged on the sheet member so as to pass through the center point of the sheet member and across the arc-shaped base lines. A total number of patterns is indicated near to an end of the template. The total number of patterns is obtained when a pattern with a pitch substantially coinciding with one of the pattern pitch measurement lines has been sewn into a circular arrangement.
