ホモテナシ

• 共箱
• 花押 — adding a box gives you the opportunity to add your 花押!
• 取合わせ: Law of non-repetition (if there's a live flower, no flower patterns; if you use a black 茶碗, you can't use a black 棗).
• 道具 are private, reflecting the 茶人's taste (→ 好み）and aspiration. A tea devotee will not reveal to others what kind of tea utensils he has in his private collection. At a tea gathering, an event based on the principle of //一期一会, the element of suspense as to what utensils will be used is essential.// (Hatakeyama Issei. Funnily, his collection ended up in a museum)
