I did buy the 'extra' lifter foot (suppose to come down on the top piece of fabric while the foot lifts to create a "clamping" action). This works about 1 out of 5 stitches. This is a new machine so I am still getting the feel for it but I am still having problems after about 400 practice and 50 real stitches. Just looking for some extra ideas. I will look at the teflon and seeing about adjusting the foot.
