Antique kimono fabric for kids

I bought these fabulous antique fabrics at 銀座円窓乃やゝ ginza marumadono yaya Ginza.

Yaya's main shop is located in Kyoto. 

These pieces are from kid kimono which is almost 100 years old. These are real silk!

I'm going to make 2 pieces of obi(kind of belt for kimono) reusing them.
