Not all 1/4 inch feet give the quilter's 1/4 inch. To check yours, take 3 strips of fabric 11/2 inches wide and sew them together. The middle strip should measure an exact 1 inch. You might have to adjust where your needle comes down to get what you need. Some quilters do that every time they start for the day and purposely cut the strips to a length they can use in a scrappy quilt
