I found kaishi with casual patterns. One is designed “iron kettles”, the other is “pairs of tea bowl and tea whisk”.

Kaishi, “pocket paper”, is made of Japanese traditional paper called washi. It is often used as a paper plate on which sweets are placed at the tea ceremony. When in kimono, kaishi is tucked inside the front of one’s kimono.

In addition, Japanese poems used to be written on it in old days, so you can use it as a memo pad, too.
How would you use kaishi?
