BERNINA #83 Circular Embroidery Attachment
This attachment is screwed into the bottom of your sewing machine, with the center of rotation either to the right or left of the needle. The attaching screw lays flat enough to allow the fabric to feed smoothly over it, allowing you to stitch circles from 1" to 5 5/16" in diamater.
When using this foot, use 2-3 layers of stabilizer 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!
