Remake a card case from obi fabric and kimono fabric

Hello. This is Rurimon, a kimono remake shop in Aobadai, Yokohama.
I remade a card case using obi fabric and kimono fabric. It's the same combination I used when I remade a bag previously. The exterior is black obi fabric, and the lining is red Oshima tsumugi. It's a subtle yet stylish card case with a glimpse of elegance. It can be made from leftover fabric from tailoring Western clothes. I don't want to waste even the smallest piece of fabric.
