Guests fold their kobukusa ensuring the wasa (a seamless and folded side of a fukusa or a kobukusa) part should be folded over to the left, and turn the folded part (wasa) downward before putting it into the inside of the front flap of kimono with kaishi (Japanese tissue) and a fukusa (a small silk cloth used in the tea ceremony).
客側は、古袱紗のわさを左側に折り返し、新たにできた折り目の部分（わさ）を下側にして、懐紙・袱紗とともに懐中する。
