Sorry, but sashiko is hand quilting. It is all straight lines, with each stitch the same size in lenght(sic) and separation and the use of contrasting thread. When I first learned to do sashiko, tiger tape came in very handy. You can use sashiko to do all over quilting or just do sections, like a grid. Nowadays, I have heard, there are sewing machines that do sashiko. I do not remember the manufacturer. Sashiko is all about the stitch. Your favorite size of quilting needle will do. I use topricin on my hands and wrists when doing any kind of hand work. No smell or oily stain.
