This walking foot fits most modern low shank sewing machines like Brother, Babylock, and Singer. The walking foot helps feed recalcitrant fabric through evenly. We use ours on everything from slinky knits to quilts and oilcloth. Just undo the screw that holds your presser foot assembly, pop the walking foot on the needle bar, and put the screw back. The little claw on top cuddles the needle screw, so the walking foot feed dogs go up and down every time your needle does! There's a great demo here: https://www.youtube.com/watch?v=X9NZxH9eB-0
