The Distinctive Roller Sewing Machine Presser Foot is effective for preventing fabric (stretchy materials like jerseys and knitted fabrics or hard-to-feed materials like leather or vinyl) from slipping or puckering, because the presser foot rotates to feed the upper layer together with the lower layer without slippage, so the upper layer and lower layer are fed simultaneously. The Distinctive Roller Sewing Machine Presser Foot is made to fit any Low Shank Snap-On Sewing Machine. Distinctive Premium Sewing Feet are high quality sewing feet that provide the user with ease of use for tasks they could be extremely tedious if done by hand. Start sewing with the best, Distinctive Sewing Feet. The Distinctive Sewing Foot blister packaging doubles as a set of instructions. Just pull out the cardboard back, open it up and start reading. You will be sewing in no time!
