my machine is not computerized. I have a quarter inch foot/I have 1/4 inch w/the metal bar. ive used the moleskin. my quarter of an inch is 1 thread left of where the bar for the 1/4" sits. so all the stuff doesn't work. but as I was told, move the stitch to zigzag and it will move the needle to where I need the quarter inch foot to be.
