The flowers are grouped with hiraito low-twist silk thread. A subtle nuance is added by the fact that the thread is not single-colored but combines two colors. For Japanese apricot blossom, the two colors are set as red and hiwa (a bright yellowy green). For cherry blossom, hiwa and toki (a light pink) are used, or hiwa on its own. For buds, two components are bound with hiraito to the wire core, and six of these are made.
