The Janome Circular Sewing Attachment is a fantastic tool for sewing in a perfect round, ideal for sewing decorative circles up to 26 cm in diameter. The device slots into place where your bobbin cover would go on compatible models, while a spindle slides to the left to your desired radius. Placing the centre of your embroidery design or patch on the spindle, the circular attachment anchors your work on a pivot, allowing the feed dogs to move the fabric and sewing a perfect circle!
