Echo quilting is a technique in which stitched quilting lines are at equal distances around a design or motif. The Baby Lock Ruler and Echo Quilting Foot Set is a set of four feet and a specialty ankle. The feet provide a fixed interval to use when echo quilting around a motif or using rulers. When using the edge of the ruler foot, there is a 1/4” distance from the needle to the edge of the foot. The Echo Feet provide a 3/8” interval, 1/2” interval and a 3/4” interval.
