I was told to put "mole skin" (a foot product found at a pharmacy) on the 1/4 " line. It stands up high enough that your fabric won't go over it. Haven't tried yet, but am heading to the store this afternoon to get some. I have had problems with my 1/4" foot too. Thread seems to catch on it all the time, and it also wants to bend out of shape. I'm figuring that a $3 investment at the drug store will be better than a $20 + investment in my 3rd 1/4" foot.
