Sashiko

Sashiko is a Japanese technique for decorative and functional mending. Sashiko is performed manually to protect and decorate clothing. It is also easy to perform which makes learning how to sew with thread and needle more accessible.

From Wikipedia:Sashiko

Sashiko (刺し子, lit. 'little stabs') is a type of traditional Japanese embroidery or stitching used for the decorative and/or functional reinforcement of cloth and clothing. Owing to the relative cheapness and abundance of white cotton thread and indigo-dyed blue cloth in historical Japan, sashiko has a distinctive appearance of white-on-blue embroidery, though some decorative pieces may also use red thread.

• You can begin by marking clothes with a pattern or using a stencil that can be made with multiple materials such as paper or even 3D printed materials.
• The goal of sashiko is to apply short stitches alongside the patterns.
