Hemming prevents the edges from fraying and results in a clean, durable edge. W ith the Rolled Hem Foot, you can hem light to medium weight fabrics for clothing and home decorating items without having to pre-iron the fabric edges. This foot gives you a rolled hem 2mm in width. This foot does not have the opening for Pfaff’s IDT. This foot fits most Pfaff models, except for the older 300 and 900 series, and the varimatic 6085/86/87 machines.
