This is a complete kit of one standard clear ruler foot that gives 1/4-inch distance from the needle to the edge of the ruler foot, three (3) echo feet that provide a 3/8-inch interval, a 1/2-inch interval, and a 3/4-inch interval as well as three (3) couching feet that are 1.5mm, 2.0mm and 3.0mm.
Couching is a decorative threadwork technique in which threads, yarns, or other fibres are laid across the quilt and fastened in place by the machine's quilting thread giving a special touch to your quilts or any other needlework pieces and stitchery.
