I wanted to make my own smartphone case for three reasons: to have a neck strap, to have a pocket for notes, and to be made from old kimono cloth in my favourite pattern.

Today I went to the handicraft shop and bought some pigeonholes. This is to make a hole in the smartphone case so that a neck strap can be attached, and the pigeonholes will be used to reinforce the hole.

Most smartphone cases on the market only have one hole on the top for attaching accessories. I have attached pigeonholes on the top and bottom so that I can change the neck strap on both sides.

Finally, I have completed my own smartphone case made from old kimono cloth!
