Circular Embroidery Attachment #83 lets you embroider unusual and decorative circles or semicircles.
The attachment is screwed to the free-arm. The center of rotation can be either to the right or left of the needle, with the attaching screw lying flat enough to allow the fabric to feed smoothly over it. A diameter of between 1 inch and 5-5/16 inches (2.5 cm and 13.5 cm) can be set on the slide.
The fabric must be properly reinforced for circular embroidery, so 2-3 layers of stabilizer should be placed under your project. The fabric is put onto the pin at the center of the desired circle and held in place with a rubber cap to prevent shifting during sewing. The Circular Embroidery Attachment #83 can be used in conjunction with various presser feet, and will enable you to sew circles with any decorative stitches you wish, and even arrange lettering in a circle.
