If you want more precise 1/4 inch seams,I suggest a 1/4 inch foot with guide. They really help.Just put your fabric next to the guide and off you go. It also makes making a Drunkard's Path quilt block a breeze. They make them for most sewing machines brands. Give it a try. I think you will be surprised how easy it is to have a accurate 1/4 inch seam.
