One of the most important things you have to get right in quilting is a 1/4 inch seam. I have had problems with this so I was happy to see that my Brother CS6000i had a 1/4 inch piecing foot. It didn't come with the machine so I purchased it and I must say, this is really wonderful. It has this little runner on the side of the foot that helps you make a perfect 1/4 inch seam. I would recommend this foot for anyone who owns a Brother CS6000i. I am so happy with mine.
