I have three 1/4 inch feet and the best one is the one I just bought. It has the little edge going down the side so your fabric will not go pass it. So you sew exactly 1/4 inch without haveing to keep your fabric lined up with the foot. It will do different sizes also. I have the foot Patrica has and I like it also but you are limited with the sizes and it will slide under the foot. Here is a picture of the foot I just got. It is amazing. I have been using it for the Mystery Quilt we are doing and wondering what took me so long to buy it. I saw it about six months ago and thought I had enough 1/4 feet. But boy I am glad I changed my mind. Check it out.
