I love a good walking foot - be careful of the cheapies-they could turn you against them! I use mine for anything that is a little difficult to sew - especially satin and lace! Learned this while making a wedding dress and after dealing with the fabric trying to pucker, put the walking foot on, lowered the pressure on the foot and voila! no more puckers! Have you ever tried to sew minkee? Yech! But the walking foot helps a lot. By all means, get it out and use it!
