The Singer Quarter Inch Piecing Presser Foot is a must have for quilters! It is the perfect choice for sewing small projects with narrow seam allowances, such as baby clothes and doll clothes. The sewing machine foot can be used for quilting 1/4 inch seam allowances – great for piecing quilt tops. The red guidelines on the foot help you master perfect corners! Use only a straight stitch with this presser foot and make sure to turn the hand wheel toward you prior to sewing to ensure that the needle clears the foot’s opening. This is compatible with the following Singer sewing machines:- M2105, Confidence 7640, Patchwork Plus C5985Q and Heavy Duty 4423
