not all 1/4 feet are accurate as you think. It is really the position of the needle to the edge of your fabric. To test your machine cut a strip of paper 8 inches long , sew along the straight edge, then measure from the edge to the sewing line. if it is not right try moving your needle over until you achieve the 1/4 " seam. To make sure it is right from there take a strip of fabric 8"long by 21/2" wide, fold it in half, press, then sew down the fold. Open up the strip and press, if it measures2" then you have it right. Make a note of where it is or like most new machines you can set that position in so every time you turn it on, it will or should be right.Check the sewing machine manual on how to do that. I hope this helps you a little Bertha48 :thumbup:
