where are you getting the puckers? on the binding or on the quilt top, or quilt back? on older machines or less expensive ones a walking foot is a different foot that is attached to the needle uptake shaft. and it is usually a bigger, bulky atttachment. newer machines have an extra foot, that just drops down from the back, and attaches to one of the extra feet that came with your machine. yes, it really helps with the feeding in all the layers evenly, but i have still gotten puckers. usually you can just take out several stitches, and work it in. make sure you use safety pins, and pin your borders well. this helps cut down on puckers.
