袖と半襟はシルクです。
竹を青い墨絵で描いた模様です。
I sewed Akira’s nagajuban (a full-length undergarment worn under a kimono).
Sleeves and haneri (a decorative collar on an under-kimono) are
made out of silk fabric.
Its pattern looks like some bamboo painted with a blue ink.
念のため入れてみました。
結び文です。
I was not sure a nagajuban needs semamori (lucky pattern embroideries
on the back of kid’s kimono, which protects a child from bad luck)
but I put it anyway, just in case.
It is a knotted-letter.
