From Sew-Classic, you can buy a low shank foot from Jenny that will keep your fabric exactly 1/4" just made for quilting. I have found she has the best prices for both my Featherweight and Singer 66-6. My grandmother's 1930 Singer and my Featherweight sew every one of my seams 1/4" and the foot can be used on both machines. Plus, you need to adjust your speed. I did go waaaay to fast with the knee lever on the 66-6 until I got the hang of it.
