Q. Is it safe to wear even though there is only one needlework string that is seen?

A. We use many different types of stitching. Even when only a single line of stitch is seen, there is stitching underneath the top surface.
This helps the string to not get worn by the friction against the road. It is a method of raising needlework strength without putting out the seam, and the best needlework method for the leather suit.
