For use with all sewing machines, the rotary foot is effective for preventing stretchy fabrics, jersey and knitted fabrics and hard feed materials, like leather or vinyl from slipping or puckering as is a walking foot. The attachments provided with the foot include: 1) Bias tape sewing attachment - this is adjustable and enables you to attach folded bias tape up to 20mm wide. 2) Blind Hem Attachment - this enables accurate feeding of the fabric to achieve a consistent blind hem. 3) Wide Rolled Hem Attachment - this enables wide rolled hems to be sewn in the following sizes, 1/2", 3/4" and 1". All of the attachments are used whilst sewing with the even foot giving accurate feeding of any type of fabric.
