I wouldn't be able to quilt without my 1/4" foot. Before I got that foot, I used the edge of my presser foot, but it was more than 1/4" and changed the size of my quilt. My foot has a metal guide and works beautifully. I also can change the position of my needle (just a little or it will hit the foot and break the needle) and that makes a scant 1/4". Looking forward to pictures of your project.
