This kit has everything you need to get started with sashiko and boro mending. It contains 6 sashiko designs printed on green /gray cotton. Each 6" x 8" design is ready to stitch with the included sashiko needles, leather sashiko thimble, and 100 meter skein of sashiko thread. The kit also includes 1/4 meter of solid colour matching Japanese cotton fabric.
Stitch the sashiko designs, then use them and the matching fabric to patch clothing, or make a bag or other project.
